Encryption/decryption data independent two-channel judgment system and application thereof

Abstract

The invention discloses an encryption / decryption data independent two-channel judgment system and application thereof. The system comprises an embedded processor, a Protocol processing chip, a first algorithm processing chip and a second algorithm processing chip; the embedded processor is bidirectionally and electrically connected with the protocol processing chip, the first algorithm processingchip and the second algorithm processing chip respectively, and is used for carrying out policy configuration and key management on the protocol processing chip and carrying out key configuration on the first algorithm processing chip and the second algorithm processing chip; And the protocol processing chip is bidirectionally and electrically connected with the first algorithm processing chip andthe second algorithm processing chip, and is used for sending the data packet from the protocol processing chip to the first algorithm processing chip and the second algorithm processing chip for encryption / decryption operation and then returning the data packet. According to the method, the probability of operation result errors possibly caused by the fact that a single-path algorithm processingchip is adopted for operation is greatly reduced, and the risk that disk array data cannot be recovered due to encryption operation result errors is avoided.

Description

technical field [0001] The invention belongs to the technical field of computer information security, and in particular relates to an independent two-channel decision system for encryption / decryption data and its application. Background technique [0002] With the popularization of computer applications, the development of the Internet and mobile storage devices, the improvement of terminal intelligence and the increase of storage capacity, people are more and more fond of saving some private data in the terminal in the form of files. In order to protect the privacy of the user, that is, to ensure the security of the files stored in the terminal, it is particularly important to encrypt and decrypt the files. How to effectively realize the unified and safe storage, centralized management and use of documents has become a severe challenge for electronic documents. [0003] The existing data encryption / decryption method in network transmission is to use the encryption / decrypti...
