Embodiment

[0030] In this embodiment, a specific plaintext information encryption is taken as an example, and the DNA encryption system provided by the present invention is explained in detail as follows.

[0031] For the convenience of explanation, some content in the present invention is first virtualized and quantized, specifically: the information sender is Alice, the information receiver is Bob, and the encryption key is K A , the decryption key is K B (where K A =K B or K A ≠ K B ), the content of the plaintext information M is "16th—19thOctober, 2014, Wuhan, China".

[0032] specific as figure 1 As shown, the above-mentioned plaintext information is encrypted by using the DNA encryption system provided by this application, that is, the encryption method includes the following steps.

[0033] (1) Encryption rule formulation .

[0034] In this embodiment, in order to facilitate automatic conversion using a computer system, the final digital conversion of plaintext informati...

Abstract

The invention belongs to the technical field of information security in communication transmission, and particularly relates to a DNA encryption system and an encryption method. The system comprises an encryption key, an information conversion portion, an information encryption portion, an information transmission portion, a decryption key and an information decryption portion, wherein the encryption key and the decryption key are primer sequences; and information encryption refers to that information is converted and coded and then corresponds to A, T, C, G bases in DNA in a one-to-one mode according to a predetermined rule. The encryption system and the encryption method provided by the invention can realize automatic operation of corresponding code conversion, encryption and decryption by depending on biological problem setting and biological technology development and by being matched with development of corresponding computer information technologies at the same time, have the characteristics of good compatibility with other encryption methods, high automation degree, simple key, high password cracking difficulty, safer information transmission and the like, has good application values, and can provide better reference for other new encryption systems at the same time.

Description

technical field [0001] The invention belongs to the technical field of information security in communication transmission, and in particular relates to a DNA encryption system and an encryption method. Background technique [0002] Today's society is an information society. With the mass dissemination of information, information security and confidentiality work is particularly important. [0003] Since Adleman proposed DNA computing in 1994, people realized for the first time that the ultra-large-scale parallelism and ultra-high-density storage capacity of DNA molecules have very important potential application value, so DNA molecules have been used in the fields of computing, information storage, and cryptography. Technological research has developed rapidly. [0004] As a new branch of cryptography development, DNA cryptography is in the initial stage of exploration in both theory and practical application, and is far from mature. And because DNA cryptography is an inte...
