Method For Implementing Encryption In Storage Card, And Decryption Method And Device |
摘要 |
A method for implemented encryption in a memory card, and a decryption method and device, and the method includes: receiving an input encryption key; requesting a subscriber identity card for authenticating the encryption key; after the authentication is successful, using the encryption key to encrypt plaintext data selected in the memory card the to generate encrypted data; generating encryption status information, wherein the encryption status information describes non-confidential information of the encrypted data. By using the encryption key in the subscriber identity card to encrypt data in the memory card, a user can freely select the data to be encrypted in the memory card, thereby enhancing data security in the memory card, facilitating the user operation, and enhancing the user experience. |
