Dynamic encrypting method realizing one secrete key for one file

Abstract

The invention pertains to the technical field of computer encryption, more particularly relates to a dynamic encrypting method realizing one secret key for one file. The encrypting method comprises the following steps: (1) according to the agreement of the information encrypting party and the information decrypting party, an encryption factor program module establishes a secret key tunnel; an encryption factor is obtained by extracting the state information of the information encrypting party and the information decrypting party and the agreement between the two parties, and then the encryption factor is respectively mapped in 8D space and 64D space, thus obtaining two spatial positions; and the coordinate values corresponding to the two spatial positions are the extracted secret key; (2) in a system, a spatial switching program module maps a computer file to space specified by a first secret key group, thus obtaining a new mapping file; (3) in the system, a decimal conversion program module processes the mapping file according to the way specified by a second secret key group.

Description

technical field [0001] The invention belongs to the technical field of computer encryption, and in particular relates to a dynamic encryption method with one text and one encryption. Background technique [0002] Before computers appeared, information encryption had already appeared, and the earliest application was in the process of transmitting military intelligence. [0003] After the emergence of computers, especially the rapid development of Internet technology, the technology of information encryption has become more and more important. People need to quickly transmit various types of computer file information through the network. In the process of information transmission, due to various reasons, the information will be intercepted. With the continuous improvement of computer computing speed, the time and cost of decrypting the intercepted information will become less and less, and a large amount of important information is insecure. status. [0004] In the current...

Problems solved by technology

Take the banking system as an example. At present, when people conduct transactions in online banking, their information is relatively safe. It takes a long time to decrypt the intercepted information. From the perspective of decryption cost, it is not worth decrypting. However, when quantum When computers appear, all this becomes very dangerous, because according to the most complex encryption technology currently used by people, the time it takes for quantum computers to decrypt is also relatively small, and when the complexity of encryption technology increases , the time it takes to encrypt increases in series

[0005] At this stage, although a lot of information encryption technologies have been invented, they basically increase the length of the key or increase the complexity of the encryption. Although quantum encryption can meet the encryption requirements of one text and one encryption, due to cost and other technical problems, There is still a long way to go to the actual application, and there are still many technical difficulties that need to be solved
