According to the latest research data, it is estimated that the cumulative automobile sales in China will reach 26.19 million by the end of 2016. By then, the number of cars will reach an astonishing 193 million, which is also the highest data of car ownership in China. With the gradual saturation of the domestic automobile market and the maturity of the traditional car-making technology, the entire automobile industry is bound to usher in an upgrade and transformation, and today’s rapid development of the Internet of Vehicles is one of the breakthroughs in the automobile industry that are now highly anticipated by Chinese people.

The Internet of Vehicles, specifically, refers to a large-scale system network that carries out wireless communication and information exchange among V2V, V2R, V2H and V2I through electronic components such as GPS positioning, RFID (radio frequency technology) identification, sensors, cameras and image processing integrated in automobiles according to agreed communication protocols and data interaction standards.It is an integrated network that can realize intelligent traffic management, intelligent dynamic information service and intelligent vehicle control..

Many people understand car networking as car networking, but it is actually an interconnected system on every car, and its mechanism is similar to the relationship between mobile phones and mobile phone systems. After constructing the information platform, the Internet of Vehicles can integrate ITS, logistics, passenger and freight transportation, dangerous vehicles, auto repair and auto parts, car rental, vehicle management of enterprises and institutions, automobile manufacturers, 4S shops, vehicle management, insurance, emergency rescue, mobile Internet and other ecological chains.

In the existing promotion of domestic car networking products, almost all of them are large-size touch screens based on Android system. If you think about the actual functions of these products, smartphones can actually be realized. On the other side of the ocean, the car networking in the United States is fundamentally different from smart phones. It shares the information of all participants in traffic, thus making the whole transportation system smarter and more efficient, and greatly reducing accidents and congestion.

From a straight point of view, the functions that the Internet of Vehicles should realize are: when reversing, the system will remind whether there is a vehicle passing behind; When passing an intersection without a signal light, the system will warn whether there is a car in the blind area of vision; After the combination of vehicle networking and autonomous driving, vehicles can obtain the speed, direction and location information of all traffic participants through the vehicle networking, as well as the information of traffic lights and signs. Under the automatic planning of the system, traffic congestion will also be greatly reduced.

It is not what most people know: you can chat on WeChat, order a takeaway, look at the webpage and find a parking lot through the car platform.

And the reason for this phenomenon is not difficult to think of.At this stage, the domestic car networking is almost dominated by Internet companies, and Internet companies have not yet got rid of the habit of being keen on grabbing Internet portal resources. In this way, at this stage, the domestic car networking still stays in the networking of vehicles, and has not really realized the interconnection of vehicles.

From the perspective of the entire car networking industry chain, the main body is divided into four sections: end, management, cloud and big data.

The terminal, namely the intelligent display mode of V2X interaction, is responsible for collecting and obtaining the intelligent information of vehicles and sensing the driving state and environment. The derivatives include smart phones, car navigation machines, car central control screens and so on.

Tube, that is, the vehicle behavior and other conditions are transmitted to the channel of the cloud platform through data, and the interconnection problems between vehicles (V2V), vehicles and infrastructure (V2I) and vehicles and cloud (V2C) are solved, which are mainly transmitted by network operators. Derivatives include network communication sources and mobile data signals.

Cloud, that is, through the cloud platform, provides cloud services for vehicle scheduling, monitoring, management and data aggregation.

Big data platform, that is, by integrating, calculating and applying data, connects the cloud platform with 4S stores, automakers, insurance companies and Internet companies, and provides them with data-based user portraits, marketing strategies and other support services.

However, in order to realize V2X, the tube plays a key role. At this stage, whether it is the front-loading networking products of traditional car companies or the after-loading smart car networking products of various Internet companies, they are basically still in the stage of closed-door creation, and the ecology is relatively closed. Perhaps there can be some interconnection between their own products, but they have not achieved cross-brand interconnection.

Of course, the realization of V2X is not achieved by one or two enterprises. First of all, we lack a mandatory and effective platform and standard, without which there is no way. Secondly, the domestic road traffic situation has always been quite complicated, and drivers’ driving habits are also different. Even the supporting traffic facilities need to be improved, so it is easy to imagine the difficulty of connecting these infrastructures to the Internet. Further, the Internet of Vehicles also relies heavily on high-precision maps and road information to judge the lane and accurately locate it, but at present, the domestic high-precision has not been truly commercialized.

Regarding the current situation of car networking in China, Wang Qiang, CEO of Feichi Magnesium, thinks that car networking is not simply equivalent to car+Internet, and it is not just to connect the car directly with the mobile phone and pad, or to transplant the application on the mobile phone to the big screen in the car. The real car networking in the sense of front-loading should be "car+car networking", in which the car networking is a relatively closed technical system as opposed to the public mobile Internet. Because the attribute of a car is a safe and high-speed vehicle, the most basic thing is safety, not functional richness.

Therefore, if you want to connect vehicles, both safety and intelligence are indispensable, which is the first difference in concept. Many people think that the Internet of Vehicles is the central control screen, but in fact, the car is a part. Mobile phones and wearable devices should also be able to access related services on the cloud, and display different services according to the characteristics of the screen, which are uniformly provided by the cloud.

Therefore, the root cause of the domestic car networking not realizing V2X lies in the lack of relevant industry standards.However, at the 3GPP meeting in September this year, the formulation of LTEV2V standard was formally completed, and it is expected that the formulation of other standards such as V2X will be completed in March 2017. China joined the 3GPP as early as 1999, so the related standards of car networking may also be applicable in China, so the real car networking era may break out next year.

With the continuous expansion of the application scope of the Internet of Vehicles, security attacks will increase accordingly. There have been many accidents and attacks on the Internet of Vehicles, such as:

The recall of Fiat Chrysler Automobile Company in the United States. Hackers use internet technology to invade the "Uconnect" system of a moving Cherokee jeep and remotely control the acceleration and braking system, radio and wipers of the car.

The BMW ConnectedDrive digital service system was invaded, and hackers could use this vulnerability to invade the interior of the vehicle in a remote and wireless way and open the door.

Tesla Model S was invaded, and network security experts opened the door and drove away through the loopholes in Model S. At the same time, they could send a "suicide" command to Model S and suddenly shut down the system engine during normal driving of the vehicle.

In addition, the MegamosCrypto protection system of Volkswagen brands such as Audi, Porsche, Bentley and Lamborghini has also been breached.

The general network architecture of the Internet of Vehicles is based on the TSP background, and vehicles are connected to it through the car or T-box, and the App on smart devices interacts with it through Wi-Fi or other communication networks, and third-party content and service providers need to be connected to it. In addition, TSP may also be connected to some other systems within the car enterprise. Therefore, to sum up, the car networking system is vulnerable to attacks as follows:

1. Car end: infotainment system, T-box, internal CAN network and external keys.

2. Apps on mobile phones and watches

3. OBD equipment connected with CAN network.

4. Cloud server where the TSP background is located

5. Communication process, including communication from car, T-box to background, communication from App to background, etc.

Next, we will start from the perspective of multiple market segments in the field of car networking to see how they ensure the security of the car networking network.

• After loading networking equipment, it is necessary to isolate the bottom of the vehicle.

At present, the smart rearview mirror is the most common among the after-installed smart car networking products in the automobile market, while the smart rearview mirror products in China, such as Jidou Car Networking Company, connect the equipment with the CAN network of the vehicle to monitor the vehicle data. So how can the security of such a connection be guaranteed? Wang Yifei, CEO of Jidou Car Network, said that their products adopt the way of isolating the bottom of the car and adding a hardware firewall to ensure the safety of the car. In case of hacker intrusion, the hacker can’t obtain the underlying information of the vehicle, so he can’t control the vehicle, and the relevant data of the vehicle can’t be obtained and tampered with. At the software and cloud level, polar bean has also done a lot of security work, thus forming a set of all-round protection.

However, most of these rear-loading networking devices are connected by OBD interface, and hackers need to ensure that OBD devices are in the car and not far away from the car if they want to attack, so it is unlikely that hackers will attack.

• Operators of front-loading networking equipment and networking platform adopt terminal hardware protection and cloud key application.

Cai Dong, the executive vice president of Feichi Magnesium, summed up the above-mentioned vulnerable points, which are actually the three core points of vehicle terminal, server terminal and mobile terminal in the Internet of Vehicles, and their security solutions are mainly concentrated on these three key points. In the vehicle terminal, the embedded security chip is used to manage keys and encryption operations. At present, the T-BOX product ConnectedEngine adopts this technology, and the security level has been recognized by the automobile factory, which has entered the pre-assembly sequence of the automobile factory. On the server side, the security products and policies provided by the cloud service provider are configured, and the self-developed key application SDK is loaded, which is responsible for encrypting data with the vehicle-mounted terminal and the mobile terminal.

In the mobile terminal APP, the key codes are dynamically encrypted and tampered with, and the mobile terminal equipment, user account number, information and mobile phone number are bound by digital certificate technology to ensure the legal reliability of the mobile terminal. In the aspect of password application, the combination of symmetric encryption and decryption, asymmetric encryption and decryption and HASH algorithm is adopted to ensure the security and integrity of data communication while minimizing the impact on performance.

• Communication service providers adopt hierarchical security architecture to ensure the safety isolation of equipment.

As the world’s top communication service provider, Huawei is also involved in the field of vehicle networking communication, and Huawei’s Kald Lab is an organization specializing in vehicle networking security architecture. Dr. Li Tieyan from Huawei’s Kald Lab, when preaching the security architecture of vehicle networking, said: "In order to deal with all kinds of security threats inside and outside the vehicle, a new hierarchical security architecture is needed to ensure the safe isolation of vehicle-vehicle heterogeneous networks. The outermost defense line reduces all kinds of network attacks from the outside by strengthening the authentication technology between the vehicle and the outside world (V2X); The second line of defense can adopt firewall and intelligent detection technology to realize the security isolation, access control and anomaly detection between the entertainment and navigation systems in the car and the internal network of the car.

The existing vehicle architecture lacks the necessary security mechanism, which can’t avoid the hacker’s infiltration attack from the outside to the inside. It is necessary to rebuild the hierarchical linkage security architecture to realize the layer-by-layer protection of the safety-sensitive CAN(Controller Area Network) network segment and key ECU(Electronic Control Unit) components. "

As a key technology to support the hierarchical car networking security architecture, Kald Lab also shared their latest research results:

1. The CAN Bus message authentication scheme based on the international security standard ISO/IEC 9798-2 is simple and efficient, and can be integrated without adding new hardware.

2. A new anonymous authentication mechanism called Extended Dynamic Accumulator is proposed, which can ensure the true source of the message and not reveal the identity of the owner when communicating between cars and roadside facilities in the future, and effectively balance several key requirements (SAE J2945/1) put forward by SAE, such as safety, privacy, efficiency and dynamic membership change.

The future development trend of the Internet of Vehicles is irreversible. Major car companies and Internet companies are developing corresponding hardware, cloud and communication methods. However, at this stage, different modes are definitely not accessible, and data, technologies and standards of all parties should be integrated. When all enterprises in the field of car networking can follow the standards, the car networking may be able to usher in a real outbreak.

In addition, the Internet of Vehicles has been controversial since its birth, and it can be said that it has never been trusted by consumers, precisely because its security is not absolutely guaranteed. At this stage, the popularity of the Internet of Vehicles has not yet reached, and its powerful intelligent performance needs more users to use the same application before the corresponding big data can achieve the expected effect.

Let’s imagine that when the Internet of Vehicles becomes the mainstream product in the future automobile market, the resulting security problems will probably appear more frequently. Although related companies have been doing product safety maintenance and upgrading, there is no absolutely safe firewall in the world, and people certainly don’t want to drive their own vehicles at any time to be taken over by others. After all, the safety of vehicles is related to our lives, so safety is the most important thing on the road of vehicle networking development. We should not only see how the Internet of Vehicles makes our life more efficient and convenient, but ignore the dangers it may bring at any time.

　　CCTV News:The China Insurance Regulatory Commission (CIRC) announced in official website today that in order to further standardize the insurance sales service behavior, solve the problem of sales fraud and misleading that consumers are concerned about, and effectively optimize the insurance consumption environment, the China CIRC has recently issued the Interim Measures for the Retrospective Management of Insurance Sales Behavior.

　　Through retrospective management of insurance sales behaviors of insurance companies and insurance intermediaries, the Measures record and save key links in the insurance sales process, so that sales behaviors can be replayed, important information can be inquired, and problem responsibilities can be confirmed.

　　The "Measures" clarify that insurance companies and insurance intermediaries should record the whole process of insurance coverage when conducting telephone sales business; To carry out internet insurance business, retrospective management should be carried out in accordance with the relevant provisions of the supervision of internet insurance business; If an insurance company sells life insurance products with an insurance period of more than one year through a part-time insurance agency (including sales with self-service terminals and other equipment in the business premises of the part-time insurance agency), it is necessary to record and video key links; Through other sales channels, selling life insurance products with an insurance period of more than one year to policyholders aged 60 or above, or selling investment-linked insurance products, should record and video key links.

　　Insurance companies and insurance intermediaries should strengthen the protection of the personal information of the insured and the insured in strict accordance with the relevant laws and regulations, and strictly keep confidential audio-visual materials and electronic data such as audio and video recordings, and shall not leak or copy them without authorization. It is strictly forbidden to use the materials for other commercial purposes. (CCTV reporter Wang Shantao)

　　As the old saying goes, "When people live a breath, all diseases disappear." Traditional Chinese medicine believes that qi is the basic energy that constitutes life, and life lies in the movement of qi, which leads to smooth blood and long life.

　　Everyone should have felt this way. When the qi and blood are smooth, not only the body is unobstructed, the mood is happy, the appetite is good, and the sleep is fragrant, but even the work efficiency is improved a lot.

　　When the gas is not smooth, I always feel that I am stuck in my chest, feeling bored and depressed. Sometimes it will be accompanied by symptoms such as swelling and pain, poor appetite, inability to eat, abnormal stool and unsmooth defecation. I’m listless all day, and I’m not interested in doing anything.

　　Speaking of regulating qi, the first thing that comes to my mind is the qi-regulating agent strictly used by famous doctors in Song Dynasty: Simotang. Not long ago, colleague Zhang Jie took this prescription.

　　After the Chinese New Year this year, Zhang Jie often feels breathless. Whenever something happens, she feels chest tightness and chest pain, and she can’t get out with one breath. Her heart beats faster and she is panting. Sometimes she is so serious that she can’t speak.

　　There have also been some changes in my body, my stomach is swollen, but I don’t feel comfortable, and I often have constipation. I have no appetite for eating, and I feel full after eating a little.

　　With years of medical experience, Zhang Jie decided to take Simotang. After two weeks, I obviously felt that people’s spirit had improved a lot, even the voices talking to us were much louder, and the whole person became energetic.

　　Liqi Simo Decoction

　　The aforementioned Simo Decoction is called the eternal magic prescription for regulating qi and relieving adverse reactions, and it is named because it is made of four kinds of medicinal materials, namely Aquilaria Resinatum, Linderae, Areca catechu and Ginseng, which are ground and boiled into soup. It was first recorded in Ji Sheng Fang by Mr. Yan Yonghe.

　　Simotang

　　Original text: "Si Mo Tang cures seven emotions, breathes when breathing, and prevents boredom."

　　Indications: Simo Decoction is mainly used to treat the symptoms of boredom and indigestion caused by stagnation of liver qi, changes of seven emotions, wheezing and aversion to qi, and lack of temper.

　　Prescription: 10 grams of ginseng, 10 grams of linderae, 5 grams of agarwood and 15 grams of betel nut.

　　Because these medicinal materials are hard in texture, they can only produce medicinal properties if they are decocted for a long time, but if they are decocted for a long time, the medicinal properties will be reduced because the smell will be emitted. The ancient grinding method was adopted.

　　Simply put, each medicinal material is ground separately, and then decocted and taken warm, which can not only retain the medicinal properties, but also avoid excessive attack and tonic. Because the preparation method is relatively cumbersome, it is suggested to buy Chinese medicines in the market, such as Simotang oral liquid, under the entrustment of doctors.

　　Addition and subtraction of drugs: According to clinical experience, Chinese medicine removed ginseng and added two Chinese herbal medicines, Radix Aucklandiae and Fructus Aurantii Immaturus, on the basis of Simo Decoction.

　　3g of Linderae, 3g of Aquilaria Resinatum, 3g of Areca catechu, 3g of Radix Aucklandiae and 3g of Fructus Aurantii Immaturus. Grinding clothes with white wine. Therefore, this prescription is called "Wu Mo Yin Zi".

　　In order to facilitate memory, there is a prescription that says, "Four grinding can also cure the invasion of seven emotions, and ginseng can be mixed with black medicine and Penang, and it can be decocted with concentrated grinding to adjust the qi, or bitter orange can be added to make ginseng easy." Go to join in the woody bitter orange, and five grinds to drink white wine. "

　　The difference between the two: Simo Decoction and Wumo Decoction can both regulate qi, reduce adverse qi and relieve depression. The difference is that Simo Decoction is mild in medicinal properties, while Wumo Decoction is strong in medicinal properties. It is used in patients with special conditions such as asthma and fainting. It is used with caution for patients with strong body and sufficient qi, and for patients with old age, infirmity and qi deficiency.

　　Analysis of prescription: the Lindera root in Simo decoction is the monarch drug, while Aquilaria Resinatum, Areca catechu and Ginseng are all ministers drugs. Radix Linderae has a pungent and warm taste, which can promote qi circulation, while pungent can disperse qi. Wen Xin combines, while Xing San complements each other. And agarwood can reduce adverse qi and relieve asthma, and stop vomiting by warming. It mainly plays the role of reducing adverse qi.

　　Areca catechu can break the knot and eliminate stagnation, swim underwater, and play the role of breaking the knot. The three herbs complement each other, promoting qi, dispersing qi, lowering qi and breaking qi in turn, and finally achieving the effect of regulating qi.

　　However, qi is the treasure of the body, and it will also consume vital qi when it is broken. Ginseng is a commonly used medicinal material for invigorating qi, which can greatly replenish vitality, strengthen spleen and stomach, promote fluid production and soothe the nerves. So as to achieve the best effect of collecting in the scattered and supplementing in the line.

　　applied range

　　In addition to treating patients with emotional diseases caused by stagnation of liver-qi and changes of seven emotions, Simo Decoction is also commonly used to treat the following diseases.

　　Superficial gastropathy

　　The disharmony of qi between spleen and stomach leads to disharmony between liver and stomach, which is characterized by more belching and abdominal pain.

　　In Chinese medicine, it is believed that there are two kinds of qi in a person’s body, namely, temper and stomach qi, and the temper dominates the ascending, which is in charge of the subtle qi transformed by Shui Gu; Stomach qi mainly decreases, which is the turbid gas produced after the grain is decomposed.

　　One liter and one drop to ensure smooth airflow. Once the spleen and stomach are out of harmony, what should rise does not rise, and what should fall does not fall, which is manifested in the stomach, that is, the stomach is full, likes to burp, and does not want to eat. After a long time, it will damage the stomach function.

　　In Simo Decoction, ginseng is used to invigorate qi, betel nut disperses qi, agarwood lowers qi, and linden is used to temper. Promoting qi without hurting it, dispersing qi without consuming it, can reconcile the qi of the spleen and stomach, and fundamentally treat this kind of stomach disease.

　　Diseases of digestive system

　　It is characterized by abdominal discomfort, abdominal pain and bloating, abnormal stool, changes in the frequency and shape of stool, and sometimes constipation or diarrhea.

　　As mentioned earlier, the spleen and stomach are out of harmony, and qi stagnation in the middle jiao is reflected in the fact that the stomach will cause stomach diseases, which is reflected in the intestines, and the direct manifestation is the disorder of the digestive system.

　　Without the promotion of qi, decomposed grains accumulate in the intestine and are difficult to be excreted normally. Simo decoction can promote qi circulation, soothe the liver, lower qi and moderate qi, and open up digestive channels. Therefore, this prescription is often used to treat children’s functional constipation.

　　Bronchitis asthma

　　It is characterized by chest tightness, shortness of breath, dyspnea, easy cough and expectoration. At night, I will feel that my breathing is not smooth and my sleep is not real. When you are cold and overworked, your condition will get worse.

　　When the strength is insufficient and the qi is not smooth, the lung qi is easy to be insufficient, which leads to some respiratory diseases, the most common of which is bronchitis and asthma. The use of Simo decoction based on syndrome differentiation can achieve the effect of invigorating qi and promoting qi circulation, thus alleviating related diseases.

　　Precautions: pregnant women, intestinal obstruction, digestive tract surgery and other people should not take it. The specific dosage and suggestions for adding or subtracting some drugs should follow the doctor’s advice, especially for children, according to the actual situation.

　　Small coup of smoothing the air

　　Qi plays a very important role in our life, which not only determines the quality of our life, but also affects the length of our life.

　　Only by cultivating the habit of "regulating qi" in daily life can we truly "prevent the slow progress" and stay away from diseases. What are the methods of not managing qi and keeping it in order every day?

　　Massage acupoint method

　　The "Taichong point" on the sole of the foot is also known as the "Qi-eliminating point" that comes with the human body. People who are often sulking and anxious and depressed can expel the turbid qi of the body and get through the veins everywhere by pressing this point.

　　The specific location is in the gap between the first toe and the second toe, about three horizontal toes down, and the depression between the first and second metatarsals.

　　You can soak your feet in warm water for 10 to 15 minutes, then find Taichong point and press it with your fingertips to feel the acid swelling as the appropriate force. Pressing for 10 to 15 minutes before going to bed every day can regulate qi and help sleep.

　　Diet conditioning method

　　Boiling water or soup with white radish can well reduce qi, stop adverse reactions, strengthen stomach and ventilate, preferably once a week. In addition, you can use roses, orange peel and hawthorn slices to soak in water instead of tea, which can also relieve depression, regulate qi and relieve pain. Try to avoid eating spicy, stimulating, fatty and indigestible food.
