Embodiment Construction
[0031] In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0032] Such as figure 1 As shown, a hardware encrypted storage system for mobile phone private contacts is proposed, including mobile phone equipment, encrypted storage chips, key generation modules, encryption and decryption modules, private contact management modules, login authentication modules, and storage read-write modules;
[0033] The encrypted storage chip includes a core processor and a built-in EFLASH memory, which can not only provide hardware encryption and decryption functions, but also store private data that needs to be hidden in the EFlash. The Eflash area of the encrypted storage chip ensures that the storage space cannot be directly recognized by the CPU through hardware, and requires a manufacturer-specific SDK interface to read and write...
