Method for performing camouflage and camouflage removal on characters based on unrepeated keys

Abstract

The invention discloses a method for performing camouflage and camouflage removal on characters based on unrepeated keys. The method is characterized by comprising the following steps: S100: loading plaintext; S200: constructing a key dictionary; S300: determining a key block number; S400: generating UNICODE codes of plaintext characters; S500: converting the UNICODE codes into 4 bytes of Hex codes 0xyYhH, wherein when the Hex codes are less than 4 bytes, filling the bytes via 0; S600: performing camouflage on the plaintext characters by using the Hex codes, and outputting camouflage characters; S700: judging whether the camouflage of the plaintext characters is completed, if so, executing step S800, and otherwise, executing step S300; and S800: merging the camouflage characters of the plaintext characters in sequence, and outputting a camouflage text. The camouflage removal can be performed on the camouflage text by a reverse method, and the plaintext is output.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to a method for disguising and uncamouflaging data, in particular to a method for disguising and uncamouflaging characters based on non-repetitive keys. Background technique [0002] With the rapid development of computer network, computer information and computer technology, more and more people attach great importance to the security and confidentiality of information. Data encryption technology is an information security technology that is widely used and effective, and data camouflage is essentially a data encryption technology. The difference is that the camouflage of plaintext characters is to encrypt the plaintext in a certain way. Or after transformation, it is still displayed in front of the user in a readable form, so that ordinary users cannot distinguish whether the data is fake data, making the data more confusing. [0003] In the prior art, the traditional ...

Problems solved by technology

Data encryption technology is an information security technology that is widely used and effective, and data camouflage is essentially a data encryption technology. The difference is that the camouflage of plaintext characters is to encrypt plaintext in a certain way. Or after the transformation, it is still displayed in front of the user in a readable form, which makes it impossible for ordinary users to distinguish whether the data is fake data, making the data more confusing

[0003] In the prior art, the traditional encryption method is easy to be deciphered due to its regularity. Another example is the traditional RSA and DES data encryption algorithm. Due to its complexity or security issues, a simple, efficient and difficult to decipher Camouflage algorithm; In addition, there is no technical scheme for camouflaging plaintext characters in the prior art
