Embodiment Construction

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] Due to the existing file encryption technology, there are technical problems of long encryption time and low encryption efficiency.

[0046] The present invention provides a file encryption method. When an externally triggered file encryption request is received, the file to be encrypted is obtained according to the file encryption request, a virtual file of the file to be encrypted is obtained, and the file to be encrypted is obtained according to the virtual file. The file index, and encrypt the file index according to the preset encryption algorithm to obtain the encrypted file index, and store the encrypted file index. This solution encrypts the file index of the file to be encrypted, so as to realize the encryption of the file to be encrypted. Since the file index is small, when the file index is encrypted...

Abstract

The invention discloses a file encryption method, a mobile terminal and a computer readable storage medium. The file encryption method comprises the following steps of obtaining a to-be-encrypted file in a file encryption request when the file encryption request triggered by outside is received; obtaining a virtual file of the to-be-encrypted file, and obtaining a file index of the to-be-encrypted file according to the virtual file; and performing encryption on the file index according to the preset encryption algorithm to obtain an encrypted file index, and storing the encrypted file index. The file encryption time is effectively shortened and the file encryption efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a file encryption method, a mobile terminal and a computer-readable storage medium. Background technique [0002] With the development of mobile terminals, file encryption technology has become one of the key research objects of various engineers. In the Android file architecture based on the liunx file system, the existing file encryption technologies mainly include two types, namely eCryptfs (Enterprise Cryptographic Filesystem, enterprise-level file encryption system) encryption and dm-crypt encryption technology. The special feature of eCryptfs encryption is that eCryptfs is stacked on top of other file systems to encrypt files at a higher encryption level, while dm-crypt encryption technology uses the device-mapper mechanism to encrypt at the block device layer. Existing file encryption technologies are relatively safe, but these file encryption technologies all en...
