Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
The following describes an embodiment of the present invention based on its overall structure.
Example 1
The system comprises a privacy identity module, a vehicle management center, a vehicle management station and a vehicle management station, wherein for the safety of users, before the vehicle performs information interaction in an interconnection system, the vehicle is registered and registered in the management center-vehicle management station, for the anonymity, the real identity of the vehicle is not allowed to be used in the communication process, the vehicle sends the real identity of the vehicle to the vehicle management station, and after the vehicle management station receives the real identity of the vehicle, the anonymous identity of the vehicle is obtained through calculation and then is sent to the vehicle;
the information encryption module is more suitable for the interconnected system through message authentication realized by digital signature, and because the storage space is limited and the consumption degree of electric energy is considered, a certificateless aggregated signature scheme is adopted, and the method is different from the traditional aggregated signature scheme in that the difficulty problem based on discrete logarithm is adopted, bilinear pairwise operation is not used, the calculation efficiency is greatly improved, the operation speed of the system can be effectively improved, and the communication overhead is reduced;
the information interconnection module, the vehicle management station and the mobile station can be used as each node in the block chain network, when the vehicle generates an anonymous identity at the vehicle management station, the vehicle can apply for joining the network, after applying for the communication facility, the communication facility uses an aggregation signature technology to aggregate signatures and then uniformly sends the signatures to the mobile center, and then requests are sent out for endorsement, sorting and verification.
The method comprises the following steps: generating an anonymous identity, namely registering and registering a user in a management center, sending the real identity of the user to the management center to obtain the generated anonymous identity, and adding the anonymous identity into an interconnection system;
step two: the communication facility collects signatures through certificateless aggregation signature technology and sends the signatures to the mobile terminal for verification;
step three; the client carries out endorsement on the pre-sense sent by the client, broadcasts the endorsement when enough endorsement responses are collected, then sorts the transactions by a sorting node, determines the time sequence order and packaging between the transactions, finally carries out verification operation on the transactions, and writes the transactions into an account book in sequence after the verification is passed;
step four: the information interconnection, the vehicle joining the block chain network can feed back the road information at any time, and can also receive the latest road condition information, and can enjoy the entertainment functions of broadcasting, navigation and the like and communicate with other vehicles.
In the invention, firstly, an application program selects endorsement nodes according to the requirements of an endorsement strategy, transaction proposals needing to be executed are sent to the nodes, the endorsement nodes call chain codes to execute the transaction proposals, and the transactions are simulated and executed and do not really submit data to an account book; the sequencing stage receives the transactions signed with endorsements, determines the number and sequence of the transactions, packs the sequenced transactions into blocks and broadcasts the blocks to the Peer nodes for verification; the Peer node verifies the validity of the transactions contained in the received block, including endorsement policy verification and double-flower detection.
The block chain interconnection system based on the Fabric union chain system can effectively solve the problems of vehicle information interconnection and vehicle information safety privacy, can alleviate and solve the problems of road traffic jam, road faults, vehicle service sharing and the like at present, realizes safe vehicle access, and can effectively relieve road traffic pressure.
