Problems solved by technology

At present, there is no one that adopts multi-matrix and controls its change mode with passwords. The change is complex, the operation is convenient, the encryption is strong, the efficiency is high, and it can be used by multiple parties. Each has its own communication rules and cannot be known to each other, which is extremely difficult Deciphered Encryption Method

Embodiment Construction

[0016] Such as figure 1 Shown: at the beginning of s10, three pre-defined matrices are the initial positioning, pseudo code and offset matrix. Before communication, the password s11 is transmitted through undecipherable third-party means. The password can be 16-24 digits, and the meaning of the password is determined by the user Optional, meaning can include matrix left, right, up, down, row swap, column swap, row and column swap, transpose, rotation of each circle, axis symmetry, inversion, deflection, etc., and the specific amount of the above transformation Information, which is drawn up by both parties to make the password non-repeatable, so as to control the change of the matrix to generate three positioning, pseudo-code and offset matrices. Verify the password through the key, check whether it is a legitimate user s12, transform three matrices s13 according to the password, encrypt and send information s14, receive information, and decrypt s15.

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...
