The invention discloses a digital certificate revocation list updating method, an initiating terminal, a response terminal and a system, the digital certificate revocation list updating method is applied to the initiating terminal and the response terminal. When the method is applied to the initiating terminal, the digital certificate revocation list updating method comprises the following steps: sending first version information of a digital certificate revocation list to the response terminal in primary communication connection; receiving feedback information sent by the response terminal according to the first version information; and executing an updating operation or a process ending operation according to the feedback information. According to the digital certificate revocation list updating method, the security of digital certificate revocation list updating is improved, and the initiating terminal is appointed to initiate the CRL updating process, so that bidirectional information redundancy transmission is avoided, and resources are saved.
Description
technical field [0001] The present application relates to the technical field of information security, in particular to a method for updating a digital certificate revocation list, an initiating terminal, a responding terminal and a system. Background technique [0002] In order to protect the safe and reliable transmission of digital interface content, it is very important to adopt security measures for digital interface content protection. Public key infrastructure (PKI) based on digital certificates is a recognized and effective solution to security problems in network environments. Digital certificate revocation query is a key operation in PKI, and it is also a big challenge that PKI is facing. Like all forms of identification, digital certificates may become invalid before they expire, for reasons such as loss of key media or a change in user identity. When a user receives a digital certificate, he must first check whether the digital certificate has been revoked. The...
