Compared with traditional fuel vehicles, the emergence of new energy vehicles can be said to directly promote the development of automobile intelligence, more and more intelligent hardware built into the building, while the hardware configuration is getting higher and higher, the functions are more and more abundant, and even allow users to remotely manage. Remote management often requires vehicles to have networking functions, and users can achieve interconnection after binding vehicles through mobile phone APP, which also allows smart phones and smart watches to have a new practical scenario, that is, to use as a car key.
At present, the vehicle is mainly through Bluetooth and NFC way to use the mobile phone, smart watch as a car key, that is, the digital car key in part of the population, at present, many mobile phone manufacturers have supported the sensorless mobile phone key function of specific models of cars in their own wallets, such as Huawei wallet has supported the SAIC MG sensorless mobile phone car key function, which is based on Bluetooth technology, which allows users to experience the sensorless driving door, start the vehicle and other functions without pulling out the car key, without opening the mobile phone APP, without unlocking the mobile phone, This can be done without the need for an internet connection.
OPPO wallet supports mobile phone Bluetooth/NFC car key function, realizing linkage with many brands, including Xiaopeng, SAIC Maxus, Extreme Kr, Ideal, Weilai, Changan, BYD and many other car companies.
The use of mobile phones and smart watches as car keys is indeed more convenient for users to use to a large extent, alleviating the embarrassment of users losing keys, but at the same time bringing new security risks, such as property security, information security and so on. As early as 2019, Europe, the United States, the United Kingdom has been a number of incidents of theft of high-end brand vehicles through relay attacks, and there are videos on the tubing showing that someone has successfully unlocked a Model S with wires and drove it away, and even crime tools and tutorials can be purchased on the Internet, which has caused great harm to the personal and property safety of car owners. After reading this, will you still consider using mobile phones and smart watches as car keys?
For the issue of digital car key security, different industries and different manufacturers need to actively participate in it, and also need to have a unified specification to guide, here we need to mention two important alliances, one is the Global Car Connectivity Consortium (CCC), used to release the Digital Key specification, which has now reached version 3.0; the second is the Internet Financial Identity Authentication Alliance." The International Internet Finance Authentication Alliance (IIFAA) is used to ensure the security of digital keys in different scenarios. If you don't know much about IIFAA security, you can illustrate with examples that the IIFAA Trusted Digital Identity Specification has been applied and supported on more than 1.6 billion mobile phone devices, 36 mobile phone brands and more than 600 mobile phone models around the world, providing services for financial, government, online shopping and public travel applications such as Alipay, 12306, China Construction Bank, Bank of Communications, Chongqing Rural Commercial Bank, Pudong Development Credit Card, Eastern Airlines, Suning Tesco, etc., while the IFAA Alliance is safe and convenient" Fingerprint identity verification and "face recognition scheme" are currently the security ecological alliance with the widest coverage of equipment and the largest number of users in China, which shows from the side that the IIFAA car digital key has a high degree of credibility and security.
In general, the use of mobile phones and smart watches as digital car keys is safe and risky, but digital car keys are the future development trend, which can improve the interaction experience between people and mobile phones and car machines, and multi-dimensional security protection systems can ensure the safety of users' cars.
