Abstract

The invention provides an encryption method, a decryption method, a device thereof and a terminal thereof. The encryption method comprises steps of: acquiring a data length of to-be-encrypted data, a preset encryption length and an initial encryption position; judging whether the preset encryption length is smaller than the data length of the to-be-encrypted data; and if the preset encryption length is smaller than the data length of the to-be-encrypted data, encrypting the to-be-encrypted data from the initial encryption position according to a preset encryption rule. In this way, by locally encrypting the data, encryption efficiency of the data can be increased, so when the locally encrypted data is decrypted, efficiency in decrypting the encrypted data can be increased, thereby reducing encryption and decryption time.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to an encryption method, a decryption method, an encryption device, a decryption device and a terminal. Background technique [0002] At present, when encrypting data, all the data is encrypted, but when encrypting all the data, the encryption time is relatively long, and when the encrypted data is decrypted, it also takes a relatively long time, which leads to Encrypting and decrypting data is inefficient. [0003] Therefore, how to improve the efficiency of encrypting and decrypting data, so as to shorten the time of encryption and decryption, has become an urgent problem to be solved. Contents of the invention [0004] Based on the above problems, the present invention proposes a new technical solution. By partially encrypting data, the efficiency of data encryption can be improved, and when the partially encrypted data is decrypted, the encryption efficiency can al...
