Problems solved by technology

[0002] With the rapid development of information networks, the dissemination of information is becoming more and more convenient, and the speed and uncontrollability of information diffusion are becoming stronger and stronger. Various commercial documents, military documents and other important secrets are also more and more transmitted through the network. , for these confidential files, they are usually encrypted before transmission, but if the encryption method is wrong, these confidential files are likely to be decrypted and stolen, often causing irreparable losses

Embodiment Construction

[0022] see figure 1 , the preferred embodiment of the encryption method based on DNA technology of the present invention is used for encrypting the information that needs to be encrypted, and the encryption method is implemented by an encryption system 50, and the encryption system 50 includes a plaintext conversion unit 51, a matrix conversion unit 52 , a primer generating unit 53 , a DNA object synthesis unit 54 and a key making unit 55 .

[0023] see figure 2 , which is a flow chart of encrypting by the encryption method, which includes the following steps.

[0024] Step 11, the plaintext conversion unit 51 converts the plaintext of the information to be encrypted into image 3 The binary sequence shown, and then divide each 128 bits of the converted binary sequence into a group, and fill up with 0 if it is less than 128, so as to obtain multiple groups, and the binary numbers in each group are arranged as follows Figure 4 The 4x32 information matrix is ​​shown.

Abstract

A DNA technology based encryption method includes steps of converting plaintext of a to-be-encrypted message into binary sequences and dividing the binary sequences into a plurality of groups and arranging each group of the sequences into an information matrix; converting each two bits of the matrix into a corresponding basic group so as to converting the information matrix into a basic group information matrix; extracting a DNA sequence from a random position in a network gene pool and arranging the DNA sequence into a basic group converting matrix, performing conversion on the basic group information matrix by using the basic group converting matrix so as to obtain an encrypted basic group information matrix, unfolding the encrypted basic group information matrix so as to obtain a basic group information sequence; generating a primer for the basic group information sequence and adding the primer to the front part and the rear part of the basic group information sequence so as to obtain a complete DNA sequence; and synthesizing a corresponding DNA entity according to the DNA sequence by utilizing a biochemical synthesizing method.

Description

technical field [0001] The invention relates to an information encryption method, in particular to an encryption method based on DNA technology. Background technique [0002] With the rapid development of information networks, the dissemination of information is becoming more and more convenient, and the speed and uncontrollability of information diffusion are becoming stronger and stronger. Various commercial documents, military documents and other important secrets are also more and more transmitted through the network. For these confidential files, they are usually encrypted before transmission, but if the encryption method is wrong, these confidential files are likely to be decrypted and stolen, often causing irreparable losses. Contents of the invention [0003] In view of the above, it is necessary to provide an encryption method based on DNA technology that is difficult to be cracked. [0004] An encryption method based on DNA technology, comprising the steps of: ...
