Abstract

The invention discloses a data encryption method and device. The method comprises the following steps: acquiring first target time, a target location and to-be-encrypted data in parameter data; selecting any time from a historical time period before the first target time as migration time; generating first offset information based on the offset time and the target location; acquiring an environment information array of the target location within the offset time, and selecting multiple target environment variables from the environment information array for combination to generate a key; and encrypting the to-be-encrypted data based on the first offset information and the key. The technical problem of data leakage caused by the fact that more reliable encryption cannot be provided for data in the prior art is solved.

Description

technical field [0001] The present application relates to the field of network technology and security, in particular, to a data encryption method and device. Background technique [0002] After years of development, information security technology has developed from cryptography to hiding technology. However, in the application process of information hiding technology, various information hiding algorithms can no longer reliably encrypt data information by hiding secret information. The attacker can easily crack the information hiding algorithm. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The embodiments of the present application provide a data encryption method and device to at least solve the technical problem of data leakage caused by the inability of the prior art to provide more reliable encryption for data. [0005] According to an aspect of the embodiment of the present application, a data encr...
