摘要/Abstract

摘要： 针对普适环境中的密钥管理问题,利用椭圆曲线加法群设计了一种新的基于身份的密钥管理方案。新方案利用门限秘密共享机制构建了分布式密钥生成中心,并设计了私钥更新、主密钥分量更新和会话密钥协商策略。与现有基于身份密钥管理方案相比,新方案具有更强的安全性和更高的执行效率。

关键词: 普适计算,密钥管理,基于身份的密码体制,门限机制

Abstract: Considering the key management in pervasive computing environments,this paper proposed a novel identity-based key management scheme from additive elliptic curve group．It employs the secret-sharing technique to construct distributed private key generators,and designs the methods of updating private key,updating host-key shares and negotiating session key．It can achieve higher security requirements and has higher efficiency compared with available identity-based schemes.

Key words: Pervasive computing,Key management,Identity-based cryptography,Threshold mechanism
