Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of virtual key share 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 is based primarily upon PKI (Public Key Infrastructure, public key
Infrastructure) technical system design, this design needs by the way that under the conditions of online, mobile terminal is obtained by the number of lock end such as automobile
Word certificate, automobile obtain the digital certificate of mobile terminal, realize the two-way authentication of mobile terminal and vehicle, the key that then conversates association
The interaction of quotient, operation system.Virtual key in the prior art, which has the disadvantage in that, needs the online exchange for carrying out certificate, right
The sensibility of network is higher；It is higher to CA system (certificate center) server requirement；It will appear man-in-the-middle attack, certificate carried out
It kidnaps；With the increase of number of users, construction and operating cost are high, system complex.In addition, the sharing based on this virtual key
System is also dangerous.
Therefore, it is badly in need of a kind of highly-safe virtual key share system and method.

End is verified, if being verified, generation is sent to target terminal by lock end session key and is verified, if being verified,
Then unlocked according to the unlock instruction that target terminal is sent；
Offline communications module, for terminal and by the transmission of information between lock end.
The virtual key share system of the present embodiment, user terminal and target terminal pass through interaction public key and carry out identity information
Verifying, be only proved to be successful, target terminal could be unlocked using the identity information of user terminal by lock end, have structure
Simple, the safe and convenient to use advantage with method.
As Fig. 1 is used for root when it is implemented, the virtual key share system of the present embodiment further includes key management apparatus
User terminal identification key pair is generated according to user terminal ID, and is sent to the user terminal；It is also used to generate quilt according to by lock end ID
Lock end tagged keys pair, and be sent to by lock end；It is also used to generate target terminal tagged keys pair according to target terminal ID, concurrently
It send to target terminal；
User terminal, be also used to carry out received user terminal identification key pair with the key pair that itself generates it is compound,
Obtain user terminal key pair；
It by lock end, is also used to be carried out received by lock end tagged keys pair with the key pair that itself generates compound, obtains
By lock end key pair；
Target terminal, be also used to carry out received target terminal tagged keys pair with the key pair that itself generates it is compound,
Obtain target terminal key pair.
It is to add to the public key point of cipher key pair that key pair, which carries out compound mode, and private key mould adds.
In the virtual key share system of the present embodiment, target terminal and by lock end when carrying out information transmission, do not need
Third-party on-line authentication, but target terminal and information transmission is directly carried out by lock end, reduce interactive step, interaction data
Amount and operand, pass through identity, the double verifying of session key, it is ensured that the safety of unlock；Offline communications module is used simultaneously
It carries out target terminal and by the transmission of information between lock end, reduces whole system to the sensibility of network, improve and used
Safety and reliability in journey.
When it is implemented, key management apparatus is by user terminal ID or target terminal ID or by any in lock end ID
Default matrix is substituted into, which includes matrix public key and matrix private key, is respectively used to generate public key and private key, forms key
It is right；User terminal key pair, target terminal mark are generated using CPK (Combined Public Key, Conbined public or double key) Encryption Algorithm
Know key pair or by any of lock end tagged keys centering.CPK Encryption Algorithm specifically can be the close SM2/SM3/SM4 of state and
It is any one or more in AES/DES/ECC/SHA1/SHA256, it is selected as needed.It may be implemented to surpass using these algorithms
The production and distribution of extensive tagged keys can satisfy the needs of more users with the resource of very little；Also there is memory space
Need less, the advantages that operational efficiency is high, processing energy is big.
When it is implemented, offline communications module is bluetooth module.Bluetooth module can be realized short distance, low-power consumption it is offline
Communication has the advantages that at low cost, realization is easy, convenient for popularization.
