一种基于身份的多信任域认证模型

在分析了现有认证框架存在的问题的基础上，提出了一种基于身份的多信任域认证模型．该模型以基于身份的密码体制为基础，避免了基于传统PKI的认证框架的诸多弊端，实现了跨信任域的身份认证和资源访问主体的匿名性，并利用CK模型对该模型的身份认证和匿名性安全进行了详细的分析和证明．分析表明该模型是安全且满足安全需求的．

An Identity-Based Authentication Model for Multi-Domain

In this paper, the authors considers the especial requirements of the authentication model in multi-domain environments. He analyzes the problems of existing authentication frameworks, and proposes an identity-based authentication model for multi-domain. The model is based on identity-based public key cryptography, so as to overcome some problems posed by traditional authentication model based on PKI. Moreover, entity authentication for cross-domain and anonymity for subiect is supported in the model. Especially, by using the modular approach under the CK-model, the security of entity authentication and anonymity is analyzed. It is showed that the proposed model is secure and could achieve the security requirements.
