Problems solved by technology

This method is to use arbitrary base numbers and integer calculation formulas to find three parameters and use them as three-dimensional coordinate points, and then store the original data in the three-dimensional coordinate points, that is, store them in x, y, z coordinate points to form a new Three-dimensional data arrangement achieves the purpose of data encryption, and overcomes the shortcomings of previous asymmetric encryption calculation formulas, which are complicated by word length restrictions and prone to decimals

Abstract

The invention relates to the field of computer scrambling coding theory and communication, and provides a multiparameter three-dimensional digital encryption method, which includes the following steps: based on original data in a computer storage and according to the arbitrary carry number and integer computational formula, a plurality of encryption keys of original data can be obtained through the FPGA, then the original data can be stored in a three-dimensional coordinate enciphered data represented by encryption keys, and besides an encryption key and original data storage sequence linear list is formed and communicated with enciphered data through a network, so that the data encryption is realized. The encryption method adopts a simple computational formula, has many encryption parameters and great difficulty in decryption, and overcomes the deficiencies that the former asymmetric encryption computational formula is complex, is limited to word length and causes high possibility of forming decimals as no decimal is formed in the calculating parameters.

Description

technical field [0001] The invention relates to a multi-parameter three-dimensional digital encryption method, which belongs to the field of computer security coding theory and communication. Background technique [0002] Encryption and decryption technology processes information to obtain information (or data) that is not easily broken. In order to prevent information from being destroyed or attacked, many people study encryption technology. As early as the 1960s, Americans developed the RSA encryption method (RSA is the initial letter of three people's names). In the 1990s, the elliptic curve encryption method appeared. At the beginning of the 21st century, the HILL encryption method and the EAS encryption method appeared. [0003] At present, the world's encryption technology is developing rapidly. In the 21st century, matrix encryption technology has become the mainstream. Among different encryption methods, rotation matrix encryption is mentioned. In fact, there are on...
