Abstract

The invention relates to the field of hard disc encryption, in particular to an SATA hard disc device encryption method and system. The method comprises the following steps that a hard disc device is electrified, whether a secret key storage module exists is detected, if the secret key storage module exists, a device encryption module completes secret key loading, and if the secret key storage module does not exist, the step finishes; the device encryption module judges whether a secret key is correct, if the secret key is correct, the hard disc and a computer complete read and write functions, and if the secret key is incorrect, the computer and the hard disc cannot complete read and write. The system comprises the device encryption module for completing encryption and / or decryption of the data transmission between the hard disc and a main board and the secret key storage module for storing the secret key. By means of the SATA hard disc device encryption method and system, the whole disc encryption of the connected hard disc device is achieved, and sensitive data leakage caused by loss or theft of the hard disc device is avoided.
