Key negotiation method, security guiding method and system for self-encryption solid state disk

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. 本发明涉及固态硬盘技术领域，公开一种自加密固态硬盘的基于密码钥匙的密钥协商方法、安全引导方法。所述密钥协商方法通过密钥钥匙与自加密固态硬盘协商产生会话密钥，通过会话密钥加密或解密KEK，大
