Embodiment Construction

[0064] Before describing the method, device and system of the present invention in combination with specific embodiments, firstly introduce several concepts involved in the complete certificate authentication process, and understand the functions and relationships of each subject in the authentication process through a specific example.

[0065] In an e-commerce activity, all entities participating in the transaction must clearly indicate their identities. Only when this mutual trust relationship is established can the transaction be carried out normally. The digital certificate is an effective means for participating entities to show their identity to each other.

[0066] Asymmetric encryption algorithm is the basis for realizing digital certificate. The algorithm uses a private / public key pair, and data encrypted with the private key can only be decrypted with the corresponding public key, and vice versa. Typically, a CA signs a certificate so that it confirms that the publ...

Abstract

The method comprises: pre-setting certificate revocation list (CRL) in the real-time distributor; the certificate use end send a CRL download request to the real-time distributor; the real-time distributor enquiries the CRL corresponding to the download request in its saved CRLs, and returns the CRL to the certificate user end.

Description

technical field [0001] The invention relates to the management of digital certificates, in particular to a method, device and system for accessing a certificate revocation list. Background technique [0002] With the popularity of the Internet, various e-commerce activities are developing rapidly. In order to ensure the security of electronic transactions and payments on the Internet and prevent fraudulent behavior in the process of transactions and payments, a trust mechanism must be established on the Internet. This requires that buyers and sellers participating in e-commerce must have legal identities and be able to be verified effectively and correctly online. [0003] Based on the public key infrastructure (PKI, Pubic Key Infrastructure), the use of asymmetric encryption public / private key pairs and certificates is an effective means to meet the above requirements. Data encrypted with a private key can only be decrypted with the corresponding public key, and vice versa...
