Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of virtual key two-way authentication system and methods.
Background technique
Internet of Things is considered as the third time revolution that IT industry develops after computer, internet by people, general
Make it possible all things on earth interconnection in the network characteristic of change.Smart home, car networking, artificial intelligence everything behind just
It is that Internet of Things is accelerating landing, fast-ripenin, the arrival of the internet of things era is unquestionable.The basis of Internet of Things and core are still
It is so internet, is extension and expansion based on the internet, and cloud computing, mobile Internet, intelligent terminal etc. then exist
The architectural framework of help Internet of Things becomes more to enrich full.Internet of Things has become our times new round economy and development in science and technology
One of strategic high ground, develop Internet of Things and have important practical significance for promoting economic development with social progress.However,
Just because of internet of things for the natural inheritance of internet, so that all kinds of malicious attacks initiated for internet start
Internet of things field is spread to.
By taking car networking as an example, car networking is core application of the Internet of Things in intelligent transportation field, and car networking project is intelligence
The important component of traffic system.Car networking be by the sensing equipment, mobile unit and communication module being installed on vehicle,
Using mobile communication technology, auto-navigation system, intelligent terminal and information network platform etc., realize the road Che Yu, Che Yuche,
Vehicle is connect with the overall network of people and vehicle and application platform, and is analyzed by business platform information, handled and dug
More abundant, comfortable, safe and efficient vehicle operation and integrated information service are realized in pick.
As the acceleration of mobile Internet and car networking technology is universal, bluetooth is led to offline as a kind of short distance, low-power consumption
Letter technology, has at low cost, realizes and is easy, the characteristics of convenient for promoting, the life of the combination of Bluetooth technology and automotive engineering to automobile
Production, use, service band carry out bigger convenience, and Bluetooth technology has very big in the efficiency of communication and low-power consumption, security fields
Progress.
The one kind of bluetooth key as virtual key will become the standard configuration of next-generation automobile.Virtual key can also be with
It is called digital key, mainly utilizes near-field communication technology, user is allowed to pass through smart phone or wearable smart machine
Unlocking, locking etc. to carry out car door, door etc. operate.Digital key in addition to bigger convenience can be brought to user,
The digitized essence of body is but also digital key becomes the infrastructure of many new car networking application and service, such as automobile is total to
It enjoys, timesharing lease, business of hiring a car is delivered to boot etc. fastly.Current many automakers are constructing digital key solution
When there is no adequately it is considered that bluetooth key is a very important service in fact.And how to ensure this and service
Safety, then need automaker just to pass through the different use-cases under structured walk-through scene in the initial design phase, analyze
Specific demand for security, to select suitable technology and standard to construct safe digital key system.There are also critically important
Any is that the life cycle of bluetooth key service is longer (5~10 years), if bluetooth will also be determined by having complete updating ability
Safety of the key service in whole life cycle.
The technical solution of the virtual key of current research be based primarily upon PKI (Pub l i c Key I nfrastructure,
Public Key Infrastructure) technical system design, this design needs by the way that under the conditions of online, mobile terminal is obtained by lock end such as automobile
Digital certificate, automobile obtain mobile terminal digital certificate, realize mobile terminal and vehicle two-way authentication, then conversate close
Key negotiation, the interaction of operation system.Virtual key in the prior art, which has the disadvantage in that, needs the online friendship for carrying out certificate
It changes, it is higher to the sensibility of network；It is higher to CA system (certificate center) server requirement；It will appear man-in-the-middle attack, verify
Book is kidnapped；With the increase of number of users, construction and operating cost are high, system complex.
