Abstract

The invention discloses a data encryption method, a decryption method and related devices. The first key for encrypting original data is generated according to the current dynamic number, so that the first key can be dynamically self-renewed. The keys are all different, which reduces the risk of key leakage and cracking. Moreover, the first key is encrypted twice, which further reduces the risk of key leakage and cracking, ensuring the security of the original data.

Description

technical field [0001] The present invention relates to the technical field of data security, and more specifically, relates to a data encryption method, a decryption method and related devices. Background technique [0002] Encryption is a widely used information security method, and in Internet systems, security has always been the top priority. Especially for data such as customer information and transaction information, it is generally encrypted. [0003] In the prior art, the Internet system configures the key in the environment variable of the operating system, and each time the data is encrypted or decrypted, the Internet system obtains the key from the environment variable of the operating system. However, at present, the keys configured in many Internet systems are fixed, and as the use time prolongs, the risk of key leakage and cracking will increase, resulting in a decline in data security. [0004] Therefore, there is an urgent need for a data encryption and de...
