Abstract

Embodiments of the present application provide a key authorization method, device, and digital signature system. The key authorization method includes: the requesting device generates a key application factor, and sends the key application factor to the target device, wherein the key application factor is used To apply for the use authority of the digital signature key; the target device uses the received key application factor and the key factor stored in itself to generate the authorization key factor, and sends the authorization key factor to the rights management server, wherein the authorization key factor It is used to indicate that the target device agrees to authorize the use authority of the digital signature key to the application device; the authority management server hosts the authorization key factor to realize the authorization of the digital signature key. With the help of the above technical solution, the embodiment of the present application solves the insecure problem of key authorization existing in the prior art.

Description

technical field [0001] The present application relates to the technical field of information security, and in particular, to a key authorization method, device and digital signature system. Background technique [0002] With the rapid development of Internet business, a large number of transactions are carried out online, and electronic signatures have gradually become an important means of online transactions. [0003] Currently, existing electronic signatures can be implemented through collaborative digital signature methods. [0004] However, for the existing collaborative digital signature method, only the holder of the key can sign. When other people want to sign, the holder needs to use his own key for the requester, which may cause insecurity problems caused by malicious copying of the key. SUMMARY OF THE INVENTION [0005] The purpose of the embodiments of the present application is to provide a key authorization method, device and digital signature system, so as...
