中文摘要: |
自动信任协商(ATN)是通过交换数字证书和访问控制策略在陌生人之间建立信任关系的一种重要手段。在协商过程中,可能存在协商模式过于复杂而无法完成协商、用户证书里的敏感信息泄露、因加密算法安全强度不足而遭受攻击等问题。针对这些不足,本文提出了一种基于非对称加密的自动信任协商模型,该模型采用灵活的证书格式、分步骤的证书交换等手段来满足访问控制策略的要求,采用非对称加密技术对传输消息进行加密,防止信息泄漏。 |
英文摘要: |
Automatic trust negotiation is an important means of establishing trust relationships between strangers through the exchange of digital certificates and access control policies. In the negotiation process, there may be some problems, such as too complicated negotiation mode to complete the negotiation, disclosure of sensitive information in the user certificate, and attack due to insufficient security strength of encryption algorithm. In view of these deficiencies, this paper proposes an automatic trust negotiation model based on asymmetric encryption. The model adopts flexible certificate format, step-by-step certificate exchange and other means to meet the requirements of access control policy, and adopts asymmetric encryption technology to encrypt transmitted messages to prevent information leakage. |
