摘 要: | 在分布式环境中,信任管理是最常用的访问控制方法。信任管理包括形式化安全策略和安全凭证,决定是否特定的凭证集合可以满足相关的策略以及委托信任给第三方。在信任管理中一致性证明是关键,而证书链发现又是一致性证明的关键。证书链的发现是基于证书的格式与存储的。因此,对信任管理中证书的存储和查找算法进行了研究,并指出了信任证书存储和查找算法的发展方向。

Abstract: | Trust management is a common approach on access control in distributed environments. Aspects of the trust management prob- lem include formulating security policies and security credentials, determining whether particular sets of credentials satisfy the relevant polices, and deferring trust to third parties. Proof of compliance is a key problem in trust management problems, and certificate chain discovery is a key problem in proof of compliance. Certificate chain discovery is based on the format and the sto... |
