The key generation device includes: a system information module configured to store system information of the key generation device; a key generation module configured to generate unpredictable information as a key in an orderly and controllable manner according to the system information, and use the generated serial number as the corresponding key serial number; and a transmission module configured to send the key serial number to the paired key generation device, wherein the paired key generation device stores the corresponding key number corresponding to the system information Second system information.

Description

technical field [0001] The present invention relates to the field of information security, and more specifically, the present invention relates to a key generation device, an encryption device, a key generation and distribution system and an information security delivery system. Background technique [0002] The importance of information security is undeniable. In today's highly developed computer and global interconnected communication technology, the safe transmission and storage of information is very important. Information encryption is an important means to achieve information security. The file is converted into ciphertext through information encryption technology. If the ciphertext can only be deciphered by the authorized party to ensure that it is meaningless to illegal interceptors, the information can be in the form of ciphertext, making full use of the convenience of existing communication technology. safe transfer between. Therefore, an encryption method with ...
