Abstract

The invention discloses a data management method and a related device, which can be applied to a cloud file storage process. Verification information is obtained; the verification information is processed according to a preset rule to generate an encryption key, and the encryption key is used for being compared with a target key in a trusted execution environment to obtain a result identifier; then the result identifier is obtained from the trusted execution environment; and when the result identifier indicates that the encryption key is matched with the target key, target data is encrypted based on the target key to obtain encrypted data. Due to the fact that the target key is only stored in the trusted execution environment, direct invasion of malicious codes is avoided, the output content of the trusted execution environment is the result identifier, the influence of the authority management process on data safety is avoided, and the safety of data management is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data management method and related devices. Background technique [0002] With the development of Internet technology, more and more data content appears in people's lives, and the corresponding personal mobile devices store a large amount of important private data of users. Once the user's mobile phone is lost, or the lock screen password is cracked, personal Important data will be leaked. Therefore, it is necessary to separately encrypt and store the important data of the user on the personal device. However, since the application scenario of important data encryption storage is to protect the security of important private data even when other people physically touch the mobile phone and can unlock the screen. Therefore, a stronger local encryption scheme on mobile devices needs to be designed. [0003] Generally, the data content is stored in the form of an en...
