Financial data encryption method and system, financial data decryption method and system, equipment and storage medium

Abstract

The invention provides a financial data encryption and decryption method, system and device and a storage medium, and the method comprises the following steps: a server receiving data information sent by a client, wherein the data information comprises plaintext data and label information; setting a first secret key according to the label information, encrypting the plaintext data to obtain first data, and storing the first secret key into a cipher machine; performing encryption calculation on the plaintext data according to a message digest algorithm to obtain second data, generating a second key, and storing the second key in a cipher machine; and storing the first data and the second data in a database. The authority of data information management and the authority of secret key management are separated, when the data information is obtained, double verification of the server side and the cipher machine needs to be carried out on the client side, and the safety of the data information is improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a financial data encryption and decryption method, system, device and storage medium. Background technique [0002] With the continuous development of network technology, mobile Internet has gradually become an indispensable part of people's daily life. People need to realize many daily activities through the Internet, such as shopping, managing money, booking tickets, etc., thus leaving a lot of financial data information on the Internet. In order to ensure the security of financial data information, it is usually necessary to encrypt and decrypt these data. [0003] However, in the existing financial business system, when connecting to a third party, the embedded data security verification coupled in the business system forms a centralized and unified data acquisition authority and key management authority, which leads to the disclosure of the security of financia...
