本文基于可验证的门限秘密共享技术,提出一种分布式的可验证组密钥管理方案。该方案具有不依赖于网络拓扑结构的变化,在恶劣的网络攻击环境中仍能有效的更新组通信密钥。 关键词:ad-hoc 网络;组密钥管理;分布式密钥生成 A New Secure Group Key Management Scheme for Ad-hoc Networks Liu Zhiyuan Mao Shengli (College of Computer Science and Technique ,Huazhong University of Science and Technology,Wuhan Hubei 430076) (School of Computer Science and Technology, Huangshi Institute of Technology ,Huangshi Hubei 435003 ) Abstract: Based on the verifiable threshold secret sharing mechanism, a novel group key management scheme named DVGKM (Distributed Verifiable Group Key Management) is proposed in this paper, in which each entity holds a secret share and multiple entities in a local neighborhood can jointly update the group key. Key words: ad-hoc networks; group key management; distributed key generation
