Title:
SERVICE SYSTEM FOR MULTIPLE CERTIFICATE AUTHORITIES
Document Type and Number:
WIPO Patent Application WO/2021/248821
Kind Code:
A1
Abstract:
A service system for multiple certificate authorities, comprising a service client (10), middleware (11), a trust control platform (12) and a signature verification platform (13); the service client (10) sends to the trust control platform a signature request carrying a service identifier to be signed, and the trust control platform selects at least one certificate authority corresponding to the service identifier to be signed, so that a user performs signing by selecting a digital certificate of a target certificate authority; the middleware (11) reads certificate information of the digital certificate of the target certificate authority, and signs the service to be signed to obtain signature information of the service to be signed; the trust control platform (12) sends the signature information to the signature verification platform after the certificate information of the digital certificate of the target certificate authority has passed the detection performed thereon by the trust control platform; and the signature verification platform (13) verifies the signature information, and sends the verification result to the service client. Thus, it is possible to prevent the occurrence of a situation where the service interruption of a certain CA itself affects the normal use of a service system, thereby improving the signing efficiency.
