Problems solved by technology

[0005] 3. There is no optimization in the comparison and verification algorithm, which is only suitable for a small amount of comparison and verification, and cannot meet the comparison requirements of a large amount of data. The comparison time is too long, and the result output is too slow
[0006] These problems have caused the efficiency of weak password detection and reduced the human-computer interaction experience

Embodiment Construction

[0034] Such as figure 1 As shown, the present invention provides a quick comparison and search method for weak passwords, including:

[0035] (1) Import multiple weak password dictionary files;

[0036] (2) Import the encrypted password file to be verified from the application system;

[0037] (3) Encrypt the weak password dictionary, wherein single or mixed encryption is performed according to the encryption method and encryption order of the encrypted password file to be verified;

[0038] (4) Offline comparison and verification of weak passwords and encrypted passwords to be verified is performed by combining multi-threading and binary search method, so as to greatly shorten the time of offline comparison and verification.

[0039] Preferably, after the step (4), the step also includes:

[0040] (5) Perform human-computer interaction based on the results of weak password comparison and verification.

[0041] Preferably, the step (1) includes: importing a weak password d...

Abstract

In order to improve the account number encryption password comparison verification efficiency and improve the stability and the high efficiency of the application system, the present invention provides a weak password rapid comparison and searching method. The method comprises: (1) leading in a plurality of weak password dictionary files; (2) leading in encryption password files from an application system; (3) performing weak password dictionary encryption; and (4) performing off-line comparison verification of the weak password and the encryption password to be verified. Through adoption of the mode of combination of the multithread processing and the binary searching method, the weak password rapid comparison and searching method fully develop the performances of the hardware device (the oversized data volume verification and comparison be processed through cloud calculation) so as to greatly shorten the time of the encryption password comparison verification, improve the efficiency of the big data volume password verification and rapidly and effectively realize the detection of the weak passwords to allow the comparison and verification between the huge account passwords of the application system and the equal huge weak password dictionary to have realization possibility on the aspect of time.

Description

technical field [0001] The present invention relates to the field of information security technology, and more specifically, to a method for quickly comparing and finding weak passwords in application systems, which is used for efficient verification and detection of weak passwords in the system, and is generally applicable to weak passwords in various types of enterprise application systems. Password verification. Background technique [0002] Existing application systems (eg, software application systems, server application systems, database application systems, security authentication systems, etc.) usually use account numbers and passwords to perform security management such as security authentication. The account passwords of various enterprise application systems have the characteristics of wide distribution and a large number of users, and the weak password data stored in the system may reach the level of millions of records. In addition, the accounts of some users i...
