Description

technical field [0001] The invention relates to the field of information technology, in particular to a data encryption method and an encryption device. Background technique [0002] With the continuous development of mobile communication technology, the role of mobile terminals is no longer limited to making calls and sending text messages, it has been able to support file information processing, such as: document storage and reading, mail sending and receiving, saving, video recording, picture editing Wait. However, as more and more files are processed on the mobile terminal, we have to face the problem of information security on the mobile terminal. [0003] In order to solve the problem of information security on the mobile terminal, encryption applications are currently used to encrypt files in the external memory of the terminal, such as user privacy data such as video, audio, pictures or documents. This data encryption method is to encrypt existing files, generally ...
