Abstract

The invention discloses a system for encrypting a storage card by using a user identification card key, which includes a user identification card, a storage card and a management unit. The management unit includes a key authentication module and an encryption module. When the data in the memory card needs to be encrypted, the user is prompted to enter the key of the user identification card, and the key authentication is applied to the user identification card; the encryption module is used to encrypt the data that the user needs to encrypt in the memory card after the key authentication is passed. The invention also discloses a method for encrypting and decrypting the storage card by using the key of the user identification card and a terminal. The invention uses the key in the user identification card to encrypt and decrypt the data in the storage card, thereby improving user experience.

Description

technical field [0001] The present invention relates to the technical field of communication terminals, in particular to a method, system and terminal for encrypting and decrypting a memory card by using a key of a user identification card. Background technique [0002] Smartphone terminals have developed rapidly in recent years. At present, mainstream smartphones support user identification cards and storage cards, and users basically have no special protection measures for accessing external storage cards. That is to say, data security for smartphones There is a greater risk of storage at present. [0003] For smart phone terminals, how to protect the data in the storage card by using the subscriber identification card is a very important new topic, and there is no mature solution in the industry at present. The patent with the application number CN201120101853.6 discloses a method for encrypting TF cards. This scheme implements a method for encrypting the entire TF stora...
