摘　　要：为保证跨域资源访问的安全性,提出一种基于双线性映射的匿名跨域认证协议,该协议可以避免传统基于公钥基础构架的跨域认证方案中证书传递的繁琐性,以及现有基于身份的跨域认证方案中权威机构冒充内部成员进行跨域访问资源的弊端,同时具有实体追踪能力,支持双向匿名实体认证.性能分析表明该方案具有较好匿名性和安全性.The network services,such as grid computing and cloud computing,usually need to cooperate among multiply domains.This paper proposes an anonymous authentication protocol for multi-domain to ensure the safety of resource access between two domains.This protocol solves the problem that it is complex to deliver certification in the traditional cross-domain authentication based on PKI and avoids the shortcoming that the authority counter pretends to be a member to access resources in other domains in the current identity-based authentication for multi-domain.It has the ability to trace the entity and support the two-way certifications.Performance analysis shows that the proposed protocol has good anonymity and security.
