一种新的基于HECC的Ad Hoc组密钥管理方案

摘要

为了解决AdHoc网络在组密钥管理中的运行效率和安全性问题，文章提出了一种新的基于HECC公钥密码体制的组密钥协议。该方案采用基于HECC的数字签名技术和加密技术，提高了协议的安全性和运行效率。文章根据Ad Hoc网络的节点更新特点提出了有效的组密钥管理方案，并对协议的正确性和安全性进行了证明。性能分析结果显示在满足特定网络安全条件下，该协议具有设计简单、计算量有限、存储空间有限等优点。%In order to solve the problem of Ad Hoc networks in efifciency and security of group key management, we propose a new group key management protocol based on HECC public key cryptosystem. Based on the digital signature technology and encryption technology of HECC,the security of the protocol and the operation efifciency is improved. This effective group key management scheme is proposed according to the characteristics of node update in Ad Hoc network. Correctness and security of the protocol are proved. Results of performance analysis show that in special Ad Hoc network security conditions, the scheme is simple in design and requires limited calculation and limited storage space.
