本文基于可驗(yàn)證的門限秘密共享技術(shù)，提出一種分布式的可驗(yàn)證組密鑰管理方案。該方案具有不依賴于網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)的變化，在惡劣的網(wǎng)絡(luò)攻擊環(huán)境中仍能有效的更新組通信密鑰。
關(guān)鍵詞：ad-hoc 網(wǎng)絡(luò)；組密鑰管理；分布式密鑰生成
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
