Abstract

The invention relates to an electronic signature generation method and device, computer equipment and a storage medium. The method comprises the following steps: when a signature request is received, acquiring a verification private key and at least two sub-keys; the at least two sub-keys are arranged according to a preset sequence; determining a connection number between two adjacent sub-keys; linking the at least two sub-keys through the connection number to obtain a signature private key; verifying the signature private key according to the verification private key; if the verification is passed, generating an electronic signature according to the signature private key; the electronic signature is used for signing a to-be-signed file. By adopting the method, the risk that the private key is stolen can be reduced, and the security of the electronic signature is improved.

Description

technical field [0001] The present application relates to the technical field of electronic signatures, in particular to an electronic signature generation method, device, computer equipment and storage medium. Background technique [0002] With the development of digital applications, electronic signature technology has been widely used in various fields of daily life and work. In the prior art, when dealing with government affairs or business matters, electronic signatures can be used to sign electronic documents, which can reduce the need for users to go out and stamp documents during mailing, which can effectively improve work efficiency. [0003] At present, in order to prevent the electronic signature from being stolen, the electronic signature system is used to encrypt and protect the electronic signature. When signing the seal, the signature user can only execute the signature operation after correctly decrypting it through the private key. [0004] However, althoug...
