Abstract

The invention provides a key generation device, an encryption device, a key generation and distribution system, and an information security transmission system. The key generation device comprises: asystem information module configured to store system information of the key generation device; a secret key generation module configured to orderly and controllably generate unpredictable informationas a secret key according to the system information, and a generated serial number of the secret key used as a corresponding secret key serial number; and a transmission module configured to sendthe key sequence number to a paired key generation device, and second system information corresponding to the system information is stored in the paired key generation device.

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 ...
