Abstract

The invention provides a sensitive data encryption method and a sensitive data encryption device. The sensitive data encryption method comprises the steps of: acquiring sensitive data, wherein the sensitive data comprises data of a plurality of users; acquiring a unique identification parameter of each user; selecting an encryption key for each user from an encryption algorithm library according to the unique identification parameter; and encrypting the sensitive data of the corresponding user according to the encryption key corresponding to the unique identification parameter, so as to obtainan encrypted string of the sensitive data of each user. Therefore, in the embodiment, a malicious user cannot guess the key after different encryption keys are selected for the users. Especially in the case that the sensitive data of two users are identical, the character strings are different due to different keys, thus the guessing and exhaustion difficulty of the malicious user is increased, and the security level of the sensitive data is improved.

Description

technical field [0001] The invention relates to the technical field of encryption, in particular to a sensitive data encryption method and device. Background technique [0002] At present, users will encrypt sensitive data, but when the encryption algorithm is single or the encryption algorithm is public, malicious users will use methods such as exhaustion and guessing to crack the password, making the sensitive data public and affecting the user's encryption experience. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a sensitive data encryption method and device, which are used to solve the technical problems existing in the related art. [0004] In a first aspect, an embodiment of the present invention provides a method for encrypting sensitive data, the method comprising: [0005] Obtain sensitive data, including data of multiple users; [0006] Get the unique identification parameter for each user; [0007] s...
