A Study on CRL Revocation Delay of PKI
PKI中CRL撤消延迟的研究

Public Key Infrastructure (PKI) is a infrastructure of asymmetric encryption that delivers strong capabilities for services such as data confidentiality,authentication,integrity and non-repudiation to effectively mitigate various risks involved in a network environment. The PKI infrastructure ensures that the availability of a well conceived combination of services,communications methods and protocols to its constituent applications and programs. It means that the infrastructure provides a blanket to enable the interoperability of its constituent parts for available,reliable,and unobtrusive security services. In this paper,a model of CRL disribution is set up. By analyzing the revocation delay,we get the expression of revocation delay.The simulation result is also given,which proved correctness of our analysis .
