【摘要】 本文通过分析基于公钥的密钥管理技术,提出一个改进的公钥基础设施模型和相应的密钥恢复方案,旨在提供更高的安全性能和实现合法侦听功能。整个基础构架在提高系统安全性与实现合法侦听两个有冲突的问题之间寻找了一个合适的平衡点。文章最后讨论了整个构架的性能。更多还原

【Abstract】 Through analyzing existing public key based key management technology, this paper proposes an improved PKI model and its corresponding key recovery scheme for providing higher security performance and implementing supervision tasks. The whole framework aims at solving both security and lawful interception two contradiction problems at one time. Finally, the paper discusses the framework’s performance.更多还原
