混合云服务身份认证技术PKI和IBC对比分析及应用

Comparative Analysis and Application of Authentication Identity Technology PKI and IBC in Hybrid Cloud Service

混合云服务具有多样性和复杂性,跨云身份认证与管理是混合云架构中需要解决的特殊安全问题。以混合云架构为研究背景,对跨云身份认证管理的需求进行了分析;针对传统PKI体系和IBC技术在应用环境、密钥管理及密钥使用方面进行了对比分析,总结了各自的优缺点;针对PKI数字证书操作的复杂性及IBC对云环境的适应性,探讨了一种基于IBC的跨云认证模型,并对其效率及安全性进行了分析。

The hybrid cloud service has diversity and complexity, authentication identity and management across cloud is special safety issue which need to be solved in the hybrid cloud architecture. The research background of this paper is hybrid cloud architecture, the paper analyzes management requirements across cloud authentication identity; contrast analyzes the traditional PKI system and IBC technology In the aspect of application environment key management and key uses, s summarizes their respective advantages and disadvantages; Aiming at the complexity of PKI digital certificate operation and IBC adaptability to the cloud environment, discusses a kind of cross cloud authentication model based on IBC and analyses its efficiency and security.
