System and method for generating and managing secret key

Abstract

The invention provides a system and method for generating and managing a secrete key. When the system is started, identity recognition is carried out through an intelligent device. A plurality of sets of initial data are input and are mutually independent, and the initial data are stored in a safety hardware device which has the anti-fake and anti-decoding functions. A system root secrete key is generated through the safety hardware device according to a computation rule, and is encrypted to be stored in the safety hardware device. The root secrete key is dispersed through secrete key scattering factors to obtain the needed application secrete key. The application secrete key is stored in the safety hardware device, and the root secrete key is restored from the safety hardware device. In the whole system, the plaintext numerical value of the secrete key is only stored in the safety hardware device. Before having access to all safety hardware devices, the system identifies the true or fake of the safety devices. Operators are recognized by the system in the procedures of starting and operating. The generating rule of the secrete key cannot be known by laymen. The secret key data needed in the operation process exist in a cryptograph form. The system is high in safety.

Description

technical field [0001] The invention belongs to the field of information security, in particular to a system and method for key generation and management. Background technique [0002] The key generation and management system (hereinafter referred to as the key management system) is widely used in the field of information security and is one of the basic systems of information security in modern society. In various fields where keys are used, all keys in the entire system need to be obtained through different levels of key distribution processes. In this process, the top key, the system root key, is the most important and core key in the entire key management system. The security and reliability of the root key generation and management process directly determine the security and reliability of the entire system. All other keys in the system are obtained from the system root key through several key distributions. [0003] Because it is used in the field of information sec...
