摘 要: | 针对多数密钥建立协议存在中间参数泄露和私钥泄露问题,提出新的公钥共享的对称加密(PKS-SE)算法,进而维护智能电表与服务商间通信的安全。PKS-SE 算法以双线性映射、超奇异曲线为基础,构建智能电表与服务商通信的通信密钥,避免密钥托管问题。同时,PKS-SE算法减少了认证过程中交互的消息数,进而控制了PKS-SE算法的通信成本和运算成本。仿真结果表明,所提PKS-SE算法有效地实现了公钥共享。

Abstract: | Most of establishment-key protocols suffer from both session-specific temporary information attack and private key leakage issue.Therefore, a novel public key sharing-based symmetric encryption algorithm (PKS-SE) was proposed, in order to maintain the security of communication between smart meter and service providers.Based on bilinear mapping and super-singular curve, PKS-SE algorithm constructed the communication key between intelligent electricity meter and service provider, in order to avoid the key escrow problem.At the same time, PKS-SE algorithm reduced the number of required messages during the mutual authentication to only two messages, thus controlling the communication cost and operation cost of PKS-SE algorithm.Simulation results show that the proposed PKS-SE algorithm can effectively realize public key-sharing |
