Abstract

The invention discloses a key generation method and device. The method comprises the steps that at least two gene banks are obtained from a first system to be recombined, a target gene bank is obtained, each gene bank comprises a secret key and offset, and the secret keys and the offset are used for encrypting data; intercepting a gene pool with a preset length from the target gene pool to obtain a target key and a target offset; and encrypting the target key and the target offset. According to the method and the device, the technical problem that the security of data protection is not high enough due to a traditional data desensitization mode is solved.

Description

technical field [0001] The present application relates to the field of data encryption, and in particular, to a method and device for generating a key. Background technique [0002] Data desensitization refers to the transformation of certain sensitive information through desensitization rules to achieve reliable protection of sensitive data. In the case of customer security data or some commercially sensitive data, real data is transformed and provided for testing without violating system rules, such as data desensitization of personal information. This allows safe use of masked real-world datasets in development, testing, and other non-production environments, as well as outsourced environments. The symmetric encryption algorithm uses the same key for encryption and decryption. Asymmetric encryption is different from a symmetric encryption algorithm. An asymmetric algorithm requires two keys: a public key and a private key, that is, a public key and a private key. The pr...
