An analysis method and system based on password encoding rules

Abstract

The present invention discloses an analysis method and system based on password encoding rules, wherein the analysis method includes: performing mining processing according to the occurrence rules of password items to obtain association rules of password items; The iterative layered analysis process is used to obtain the first commonly used encoding rules; the rule extraction process is performed on the association rules and the first commonly used encoding rules to obtain easily decomposable encoding rules. In the embodiment of the present invention, adopting the embodiment of the present invention can expand a large number of commonly used passwords according to the password coding habits, and the coverage amount and the hit rate of the existing database are prioritized, and the encrypted passwords can be cracked extremely quickly, and the mining can also be freely expanded. Rules, freely expand the password library, and automatically adjust the coding rules.

Description

technical field [0001] The invention relates to the technical field of security authentication, in particular to an analysis method and system based on password coding rules. Background technique [0002] Due to the digitization of criminal communication methods of criminals and dangerous elements, most of the text information used in interaction has been encrypted with passwords. Even if the security agency captures the criminal evidence file information, it cannot be decrypted and effective evidence information cannot be obtained. Therefore, it is necessary to be able to analyze the priority of the encoding rules of encrypted passwords, so as to greatly improve the speed of cracking encrypted file passwords, grasp the criminal evidence of criminals as soon as possible, and improve a strong guarantee for further solving cases. [0003] Most of the current encrypted file cracking uses common passwords for exhaustive cracking or uses existing password libraries for credential...

AI Technical Summary

Problems solved by technology

This method is limited by the number of commonly used passwords and passwords, and it is difficult to cover most of the passwords used for encryption on a large scale.

[0004] The password encoding rule analysis system uses data mining technology and its own rule analysis algorithm to conduct statistical analysis on the password database, extracts common password encoding rules, and improves the hit rate of passwords. Application system for password analysis
