| description | The invention discloses signature and signature verification methods and devices based on an SM2 algorithm, equipment and a medium, relates to the technical field of cryptography, is applied to a signature end, and comprises the following steps: determining to-be-signed data, and generating a first information abstract of the to-be-signed data by using an abstract algorithm; performing blind processing on a private key in a key pair based on a random number, and signing the first information abstract by using the blind private key to obtain a signature result; and sending the signature result and the to-be-signed data to a verification end, so that the verification end generates a second information abstract of the to-be-signed data by using the abstract algorithm, and performs signature verification on the signature result by using a public key in the key pair and based on a multi-scalar point multiplication method to obtain a signature verification result, and obtaining the verification result based on the |
