Abstract

A device and method for ensuring user information security in communication equipment. The device includes a storage module, a key acquisition module, an encryption module and a decryption module. User information is stored in the storage module. The key obtaining module is used for transmitting input data to the key generating module, and then receiving a key generated by the key generating module in response to the input data. The encryption module is used for retrieving the key through the key obtaining module, retrieving the user's information from the storage module, and then using the key to encrypt the user's information to generate encrypted information. After the encrypted information is generated, the encrypted information is stored in the storage module, and replaces the user's information stored in the storage module. When the user's information needs to be used, the decryption module is used to retrieve the key through the key acquisition module, and retrieve the encrypted information from the storage module, and then use the key to decrypt the encrypted information, and then restore information about the user.

Description

technical field [0001] The present invention relates to a device used in a communication device, such as a home phone, a mobile phone (Mobile phone), a personal digital assistant (PDA), and other mobile communication devices. The device according to the present invention is used to ensure the security of a user's information, especially the communication equipment includes a Cipher key generating module, for example, a Subscriber Information Module card (Subscriber Information Module card, SIM card), by using the key generated by the key generation module, the user's information is encrypted and decrypted. Thereby, the security (Security) of the user's information is realized. Background technique [0002] Most of the existing communication devices, such as mobile phones, personal digital assistants, and other mobile communication devices, have the function of storing information, such as address book, calendar, etc., for storing user privacy inform...
