A method of masquerading and de-masquerading characters based on non-repeating keys

Abstract

The invention discloses a method for disguising and uncamouflaging characters based on non-repetitive keys, which is characterized in that it comprises the following steps: S100: loading plaintext; S200: constructing a key dictionary; S300: determining the key block number ; S400: generate the UNICODE encoding of plaintext characters; S500: convert the UNICODE encoding into 4 bytes of Hex encoding 0xyYhH, wherein, when the Hex encoding is less than 4 bytes, fill the low byte with 0; S600: use the Hex encoding camouflages the plaintext characters and outputs the camouflage characters; S700: judge whether to complete the camouflage of all plaintext characters, if yes, perform step S800, otherwise, perform step S300; S800: merge the camouflaged character sequence of the plaintext characters , to output the camouflage text; the camouflage text can be de-camouflaged and output plain text by the reverse method.

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 ...

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
