Abstract

An embodiment of the invention provides a validation method of certificate state, a certificate authenticating apparatus, a certificate revocation list (CRL) server and a CRL system; wherein the CRL system comprises the certificate authenticating apparatus and the CRL server; the certificate authenticating apparatus is used for transmitting a CRL downloading request message carrying a first CRL file identification information to the corresponding CRL server according to the obtained CRL downloading position information and validating the validity of the state of a user certificate by using a locally stored certificate revocation list (CRL) file when a received response message associated with the CRL downloading request message carries unmodified identification; and the CRL server is used for comparing the first CRL file identification information in the received CRL downloading request message with the second CRL file identification information of the corresponding CRL file on the CRL server and returning the response message carrying the unmodified identification when the comparison result is that the first CRL file identification information is the same as the second CRL file identification information. Such a technical proposal prevents from downloading the CRL repeatedly so as to ease network load.

Description

technical field [0001] The invention relates to the field of management of digital certificates, in particular to a method, device and system for verifying certificate status. Background technique [0002] With the popularity of the Internet and the development of e-commerce, people have higher and higher requirements for information security. The PKI (Public Key Infrastructure) technology based on the public key system provides security guarantees for confidentiality, integrity, and identity authentication for various applications on the network. PKI uses certificates to manage public keys, and uses a third-party trusted organization, CA (Certification Authority, certification authority), to prove the binding relationship between user identities and their public keys. Since PKI provides security protection based on certificates, only under the premise of effective management of certificates can PKI be safely and effectively applied. [0003] When deploying PKI, certificat...
