The application relates to a code scanning
authentication method, a
system and related equipment. The method adopts scanning a two-dimensional code displayed by a
client to obtain a trusted
timestamp and a dynamic address; based on the trusted
timestamp, a first signature is generated by using a first signature private key of a mobile terminal, the first signature is sent to a co-signing
server to trigger the co-signing
server to use a second signature private key stored by the co-signing
server to perform secondary signing on the first signature; according to the dynamic address, a final signature, a signature
certificate of the mobile terminal and the trusted
timestamp are submitted to a corresponding
authentication server; after
authentication succeeds, in response to a login state query request, the
client obtains user identity information and automatically completes login, the problems that in the prior art, mobile terminal key single-point storage risk is high, and after a private key is leaked, the private key is easily abused to cause authentication credentials to be impersonated are solved, the technical effect that authentication credentials impersonation risk caused by single-end private
key leakage is avoided, and the security and reliability of code scanning authentication are improved.
