The invention discloses a digital-certificate-based cryptographic operation method, which comprises the following steps of: querying a digital certificate corresponding to a login user from access equipment, and returning the found digital certificate to the login user, wherein digital certificates of each user are pre-stored in the access equipment; receiving a cryptographic operation request submitted by the login user by using the access equipment; and executing corresponding cryptographic operation according to the cryptographic operation request, and returning an operation result to the login user by using the access equipment. The invention also discloses a digital-certificate-based cryptographic operation device. The access equipment is used for storing and managing the digital certificates of the users in a centralized way, and the certificates can be updated in batches, so that the problem of insufficient storage capacity of a universal serial bus (USB) Key is solved. The users can be authenticated based on the digital certificates only by inputting personal identification numbers (PINs), so that user experiences are improved. The development of the USB Key is avoided, and the cryptographic operation is finished by the access equipment, so that the resources of user terminals are saved, and the running efficiency of the user terminals is improved.
Description
technical field [0001] The invention relates to the technical field of digital certificates, in particular to a digital certificate-based cryptographic operation method and a digital certificate-based cryptographic operation device. Background technique [0002] With the gradual deepening of the application of the Internet and business systems, e-commerce system technology enables customers who shop online to obtain business and enterprise information very conveniently and easily, but at the same time it also increases the risk of some sensitive or valuable data being misused. . How to prevent risks and enhance online security is particularly important. PKI (Public Key Infrastructure) is a key management platform that follows established standards. It can provide cryptographic services such as encryption and digital signatures and the necessary key and certificate management systems for all network applications, effectively ensuring that users identity security and data se...
