The invention discloses a method and a system for checking the revocation status of a digital certificate in a virtual environment. The method comprises the following steps: (1) multiple client virtual machines are created on a host machine, and a certificate revocation list manager is arranged in a virtual machine monitor of the host machine; (2) a certificate relying party in each client virtual machine issues a certificate revocation status check service request to the certificate revocation list manager; and (3) the certificate revocation list manager locally queries whether there is a corresponding CRL file according to the certificate revocation status check service request: (a) if there is a corresponding CRL file, the certificate revocation list manager returns the CRL file to the certificate relying parties in the client virtual machines, or the certificate revocation list manager queries whether there is a corresponding certificate serial number in the CRL file and then returns a query result; and (b) if there is no corresponding CRL file, the certificate revocation list manager downloads and verifies a corresponding CRL file and returns the CRL file, or the certificate revocation list manager queries whether there is a corresponding certificate serial number in the CRL file and then returns a query result. By adopting the method and the system, the query efficiency is greatly improved.
