摘要
针对数字证书撤销列表更新中大量结点同时请求数据造成的系统性能瓶颈,本文提出了基于P2P的数字证书撤销列表更新方案,利用客户结点的资源改善证书撤销列表的更新性能;以数字校园应用为背景建立了分析模型,对所提方案进行了分析比较。
Updating the certificate revocation list(CRL)by large amount of certificate users at the same time results in a performance bottleneck in PKI systems.By addressing this problem,this paper introduces a P2P-based CRL update scheme,which utilizes the resources on the CRL users to improve CRL update performance.Analytical models are built to compare the P2P-based scheme with other schemes in digital campus applications.
