摘要: 为解决IDAK 协议不具备前向安全性以及改进的IDAK 协议不满足密钥协商阶段全部安全属性的问题,使用双线性对技术,提出一种具备PKG 前向安全性的无证书无托管密钥协商方案,并首次将密钥协商协议应用于特定民航系统中进行模拟仿真。实验表明,该方案具备合理的对数运算尧指数运算尧乘幂运算次数,以及更高的安全强度,相比其它方案,更适用于TWLU 数据传输过程。

Abstract: In order to solve the problem that IDAK protocol does not have forward security and the improved IDAK protocol does not satisfy all security attributes in key agreement phase, a bilinear pairing technique is used to propose a certificateless and no-hosting key agreement scheme with PKG forward security. This key agreement protocol is applied to specific civil aviation system simulation for the first time. Experiments prove that the scheme has reasonable prequency of logarithm operation, exponential operation and exponentiation operation as well as stronger security, which is more suitable for TWLU data transmission compared with other schemes.

Key words: key-agreement, certificateless, no-hosting, bilinear pairings, civil aviation information system
