Electronic hardware with functions of encryption and data self-destruction and data self-destruction method thereof

Abstract

The invention discloses electronic hardware with functions of encryption and data self-destruction and a data self-destruction method thereof. The hardware comprises a flash controller and an encryption / decryption self-destruction unit which is connected with the flash controller through an ATA or SATA interface, wherein the encryption / decryption self-destruction unit comprises an encryption / decryption module, a secret key management module, a parameter read / write module, a self-destruction order detection module, a self-destruction management module, a data channel cross switch module, a nonvolatile memory interface, an ATA or SATA equipment module and an ATA or SATA host machine module. The invention can flexibly add a data encryption self-destruction module under required occasions without influencing normal operation, erase the data without a host machine, select the data erasing speed and the data erasing content, increase the reliability for erasing the data, can not destroy memory medium after erasing the data, can protect the data at all levels, increase the flexibility of data confidentiality, and control the difficulty level of decryption algorithm.

Description

technical field [0001] The invention relates to an electronic hard disk with encryption and data self-destruction functions and a self-destruction method thereof. Background technique [0002] An electronic hard disk is a hard disk composed of an array of solid-state electronic memory chips. At present, the most common electronic hard disk uses flash memory as a storage medium. As a new non-volatile storage medium, flash memory has many advantages such as high storage density, convenient portability, low power consumption, long data retention time after power failure, and good shock resistance. Electronic hard disks with flash memory chips as storage media do not have the rotating media of ordinary hard disks, so they have excellent shock resistance and a wide operating temperature. At the same time, the interface specifications, definitions and usage methods of electronic hard disks are exactly the same as ordinary hard disks, and can easily replace traditional mechanical ...
