A Digital Signal Encryption Method Using Multi-matrix

Abstract

The invention discloses a digital signal encryption method utilizing multiple matrices, comprising the following steps: inputting a password, respectively transforming a positioning matrix, a pseudo-code matrix and an offset matrix according to the password, and performing segmental calculation with the data of the pseudo-code matrix and the original text after completion Obtain segmented ciphertext, and rearrange the ciphertext according to the positioning matrix. After completion, divide the ciphertext into segments, which can be of equal length or unequal length, and then divide the divided segments according to the value of the offset matrix Perform intra-segment offset and save the offset result. The method can well strengthen the confidentiality of mutual communication, and the password-controlled matrix transformation can eliminate the security threat of a third party to mutual communication. This encryption method avoids the shortcomings of other encryption methods in the past that cannot verify the user's identity and that a set of encryption methods is easy to leak when used by multiple people, and it solves the information security problem in the communication process well.

Description

Technical field [0001] The invention relates to a digital signal encryption method using multiple matrices. Background technique [0002] The amount of modern communication information is increasing, and the number of documents is increasing. It is particularly important to ensure the security of information. In order to ensure that the information is not leaked during the transmission, a strong and practical encryption technology is urgently needed. At present, other encryption technologies have their own shortcomings, and they may be cracked after long-term communication. At present, there is no one that adopts multi-matrix and controls its change mode by password. The change is complicated, the operation is convenient, the encryption is very strong, the efficiency is high, and it can be used by multiple parties, each has its own communication rules, and it is extremely difficult to know each other. Deciphered encryption method. Summary of the invention [0003] The purpose o...
