Ciphertext data storage method and device, equipment and storage medium

Abstract

The invention is suitable for the technical field of data security, and provides a ciphertext data storage method, device and equipment and a storage medium, and the method comprises the steps: encrypting service data generated by a service system into ciphertext data, and obtaining the encryption information of the ciphertext data; according to the encryption information of the ciphertext data, data head information corresponding to the ciphertext data is generated according to a preset data head generation rule, the data head information is represented as a character string containing a plurality of characters, and the characters in the character string are used for identifying the encryption information of the ciphertext data; and adding the data header information to the head position of the ciphertext data to generate target data, and storing the target data in a ciphertext database of the service system. Based on the method, the technical problems that the algorithm used by the ciphertext is difficult to distinguish under the condition that the service system mixedly uses multiple cryptographic algorithms, the key corresponding to the ciphertext cannot be found when the key replacement scene occurs in the service system, and the relationship of the ciphertext data in the service system cannot be traced can be solved.

Description

technical field [0001] The present application relates to the technical field of data security, and in particular, to a method, device, device and storage medium for storing ciphertext data. Background technique [0002] With the development of Internet technology, in the environment of big data, data security technology has attracted more and more attention. In order to prevent sensitive data from being leaked or stolen, the online business systems currently used by many enterprises can encrypt and store the data generated by the business. However, most of the current data encryption storage schemes directly store the original ciphertext data obtained by encrypting the plaintext of the data using an encryption algorithm. In the business system scenario, the data is continuously generated, and the amount of data is large and complicated. The method of directly storing the original ciphertext data is in the business system. The data cannot record the algorithm information, ...
