Embodiment Construction

[0062] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.

[0063] The cryptographic key involved in this embodiment may be a USBKEY with cryptographic algorithms and storage functions. The self-encrypting solid-state drive involved in this embodiment supports the PCIe interface NVME protocol.

[0064] The self-encrypting solid state drive involved in this embodiment may be a solid state drive that performs full disk encryption or partition encryption. Full disk encryption refers to the encryption of user data, applications, and operating systems. The encryption key (DataEncrypt Key, hereinafter referred to as DEK) of the self-encrypting solid-state hard disk is used to encrypt all data stored in the hard disk, such as user files, s...

Abstract

The invention relates to the technical field of solid state disks, and discloses a cipher key-based secret key negotiation method and a cipher key-based safety guiding method for a self-encryption solid state disk. According to the key negotiation method, the session key is generated through negotiation between the key and the self-encryption solid state disk, and the KEK is encrypted or decryptedthrough the session key, so that the attack resistance of the key encryption key KEK and the encryption key DEK is greatly improved. According to the safety guiding method of the self-encryption solid state disk, based on the key negotiation method, the KEK is decrypted through the session key, and then the DEK of the self-encryption solid state disk is decrypted through the KEK, so that the self-encryption solid state disk is decrypted to complete guiding, and the safety of the self-encryption solid state disk is improved.

Description

Technical field [0001] The invention relates to the technical field of solid state hard disks, in particular to a cryptographic key-based key agreement method for self-encrypting solid state hard disks, a safe boot method for self-encrypting solid state hard disks, and a safe boot system for self-encrypting solid state hard disks , And a self-encrypting solid state drive. Background technique [0002] A self-encrypting solid state drive is a solid state drive that does not rely on an external encryption device. It consists of a hard drive controller and a storage medium. The storage medium includes firmware space for hard disk controller access, reserved space, and user space for storing user data. The reserved space is used to store key parameters and data structures. In order to avoid hard disk data leakage due to the theft or loss of the hard disk, by embedding a high-speed cryptographic algorithm module in the hard disk controller, the hard disk data encryption and decryptio...
