Reverse reconstruction encryption method

Abstract

The invention discloses a reverse reconstruction encryption method. The method comprises the steps of 1, acquiring a first character string to be encrypted and a second character string bound with the first character string; 2, decomposing the first character string and the second character string into subsection character strings; 3, converting the subsection character strings obtained through decomposition into corresponding coded values in a preset encoding database, and obtaining an encoding character string through intersection and reintegration according to a first identification character string; 4, conducting flashback arrangement on the encoding character string, and then decomposing the encoding character string into subsection character strings; 5, conducting digital decimal-binary conversion on each subsection character string obtained through decomposition, and then obtaining an ciphertext character string through sequential splicing of a second identification character string. The method is large in cracking difficulty and high in encryption safety and can be widely applied to the data encryption field.

Description

technical field [0001] The invention relates to the field of information security, in particular to a reverse recombination encryption method. Background technique [0002] As the network begins to infiltrate and affect all aspects of people's lives, various online businesses such as e-commerce, digital currency, and online banking are rapidly emerging, and people's requirements for confidentiality in online activities are also getting higher and higher. How to protect data security so that it does not People are paying more and more attention to issues such as being stolen, not being tampered with or destroyed. In data security, one of the more important encryption methods is to encrypt two character strings that have a binding relationship, such as encrypting the user name and password to achieve data security protection, and encrypting the CPU and hard disk numbers for software usage rights. Realize anti-piracy and so on. Most of the existing encryption methods achieve ...

Problems solved by technology

In the current technology, the main encryption algorithm only encrypts a single password field, and there are many shortcomings: 1. Each record in the data table also uses constants or variables known in the code, which are destined to be decrypted by reverse operations. Second, this type of encryption algorithm always processes the password field, resulting in the same disadvantages after encryption if the password is the same. As long as it can enter the database, it can be cracked by replacing the password with a replacement method

Therefore, the encryption method in the current technology has low security and is easily cracked.
