The invention relates to a privacy protection traffic monitoring method based on a block chain and CL homomorphic encryption, which is used for traffic monitoring of privacy protection. And the SP uploads the registration information of the vehicle and the roadside unit RSU to the block chain for storage, and deploys an intelligent contract on the block chain to assist in vehicle authentication of privacy protection. The vehicle sends the encrypted driving speed report and accident information to the RSU, and the RSU aggregates them and sends them to the SP. And the SP decomposes the aggregation speed report, calculates the average speed of each road section and broadcasts information so as to help the vehicle to select the optimal route. According to the invention, the security and integrity of registration information are ensured by using the characteristics of the block chain; the intelligent contract loads a vehicle public key table, and automatic and timely public key query feedback is provided; meanwhile, the incentive mechanism encourages vehicles to share correct information; the CL homomorphic encryption technology is utilized, conditional privacy protection is achieved, data and information safety is protected, meanwhile, the method has the advantage of being small in communication traffic, the communication cost is reduced, and low-delay communication is achieved.
本发明是一种基于区块链和CL同态加密的隐私保护交通监控方法,用于隐私保护的交通监控。SP将车辆和路边单元RSU的注册信息上传至区块链保存,并在区块链上部署智能合约,辅助隐私保护的车辆认证。车辆将加密的行驶速度报告和事故信息发送给RSU,RSU将其聚合并发送给SP。SP分解聚合速度报告,计算各路段的平均速度并广播信息,以帮助车辆选择最佳路线。本发明利用区块链的特性确保注册信息的安全与完整;智能合约加载车辆公钥表,提供自动及时的公钥查询反馈;同时,激励机制鼓励车辆共享正确的信息;利用CL同态加密技术,实现有条件的隐私保护,保护数据和信息的安全,同时具有通信量小的优点,降低通信成本并实现低延迟通信。
