The invention discloses a method, device and medium for generating a root key. The method distributes the steps of generating the root key to a first server, a second server and a third server. Wherein, the first server generates an encryption key and a decryption key, and compiles and packages the key management execution program. The second server generates the initial root key, and uses the encryption key sent by the first server to encrypt the initial root key to obtain the ciphertext of the initial root key. The third server decrypts and converts the initial root key ciphertext according to the key management execution program sent by the first server and the initial root key ciphertext sent by the second server, so as to obtain the target root key. The third server cannot obtain the initial root key and the decryption key, and the first server and the second server have no authority to log in to the third server, thus ensuring the security of root key management and improving root key security. Reliability of the safety management system.
Description
technical field [0001] The invention relates to the field of key management, in particular to a method, device and medium for generating a root key. Background technique [0002] Since the key is the core element of information security, the generation of the root key is strictly required in key security management. The root key is the topmost key and has a high value. Once leaked, it will cause serious consequences. [0003] In a commonly used key management solution, a hardware security module (hardware security module, HSM) is used for key security management. A hardware security module is a computer hardware device used to protect and manage the keys used in a strong authentication system and provide related cryptographic operations at the same time. Hardware security modules are generally directly connected to computers or network servers in the form of expansion cards or external devices. By injecting three sections of initial keys into the hardware security module r...
