Problems solved by technology
[0004] However, in the prior art, these security devices used for authentication and authorization lack interoperability at different levels, and the storage format of digital certificates on security devices also lacks industrial standards, making it possible to create certificates that can be used from different The application of the certificate work of technology manufacturers becomes very difficult, and solving this problem in the application field will inevitably increase the cost of development and maintenance; and the certificate is bound to a specific application that uses a specific application programming interface under a specific hardware structure Together, it also brings a lot of problems to the users of the client; at the same time, the mechanism that allows multiple applications to effectively share digital certificates is not yet mature, and the sharing of certificates cannot be realized in the existing technology, which makes application developers and Users are very limited

Embodiment 1
[0092] This embodiment provides a method for storing certificates. In the embodiment of the present invention, the information type of the certificate includes at least certificate information, and may further include one or both of private key information and public key information. The security device uses a smart card As an example, how to write various information of the certificate into the security device in detail.
[0093] Before explaining the method of storing certificates, first explain the initialization process of the smart card, as follows:
[0094] Step 001: Create files for storing private key information, public key information, and certificate information on the smart card;
[0095] Wherein, in this embodiment, the file ID of the file storing the private key information may be 0x4400, the file ID of the file storing the public key information may be 0x4401, and the file ID of the file storing certificate information may be 0x4404.
[0096] Step 002: Create a...

The invention discloses a method for storing certificate, belonging to the field of information safety. The method comprises the steps: a client computer sends command of selecting an application catalog file, an object catalog file, a storage catalog file and a storage file to safety equipment, and leads the certificate to be written into the storage file of the safety equipment. By the interactive operation between the client computer and the safety equipment, the certificate can be written into a specified file of the safety equipment, so that share storage of the certificate can be realized.
Description
technical field [0001] The invention relates to the field of information security, in particular to a method for storing certificates. Background technique [0002] With the rapid development of the information industry, the development of information technology not only brings great convenience to people's lives, but also fundamentally changes people's lifestyles, behaviors and values. At the same time, information technology is widely used in business. Applications have also had a huge and profound impact on economic and social development. Users can use various security devices for information transfer, storage or identity authentication. [0003] A security device (such as a smart card and USB KEY) is a device with a processor and a memory, which is mainly used for the security of information transmission and information storage, as well as auditing and identity authentication of network transmission information content, and has the characteristics of anti-attack , ext...
