| 摘要 |
An encryption/decryption method are described, which includes that a terminal performs an encryption operation according to information of an encryption sub-node of an Encrypt And Decrypt Management Object (EADMO) node of a local Device Management (DM) tree and reports to a DM server encrypted data state information generated after the encryption succeeds; and the terminal performs a decryption operation according to the encrypted data state information sent from the DM server. An encryption/decryption system and device are also described. By means of technical solutions of embodiments of the disclosure, operations are simple without causing data loss, and a problem that data of a non-local terminal cannot be encrypted is solved. |
