Abstract

The invention discloses a method for initializing an electronic signature tool. The method comprises the steps of generating first secret key information according to a secret key generation strategy and an asymmetric algorithm; generating initialized data and writing the initialized data into the electronic signature tool according to a public key contained in the first secrete key information, a public key and the version information of the public key contained in the obtained second secrete key information, a public key and the version information of the public key contained in the obtained third secrete key information and the information of the electronic signature tool; utilizing a private key contained in the third secrete key information for conducting signature on the initialized data, generating the signature data of the initialized data and writing the signature data into the electronic signature tool. The invention further discloses a device for initializing the electronic signature tool. By the adoption of the method and device, the electronic signature tool is prevented from being counterfeited, and safety is improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, and in particular, to a method and device for initializing an electronic signature tool. Background technique [0002] During the initialization process of the existing electronic signature tools, a single asymmetric algorithm is often used to generate multiple key pairs built into the electronic signature tools, and the above generated key pairs are used to generate signature data, which is used as a bank server to verify the electronic signature. However, the method of using a single asymmetric algorithm to generate a key pair has certain security risks, that is, the algorithm used in the key pair built in the electronic signature tool is easy to be cracked, and the electronic signature tool is easy to If it is counterfeited, the security of electronic signature tools needs to be further improved. SUMMARY OF THE INVENTION [0003] The present invention aims to solve the above pro...
