Problems solved by technology
[0003] In the prior art, dictionary files are generally used for brute-force cracking to identify users’ weak passwords. However, this brute-force cracking method needs to rely on a large number of passwords in the dictionary file and constantly try various passwords and encryption algorithms. Large volume and low efficiency

[0048] Specifically, see figure 2 , a specific implementation of step 120 includes the following steps:
[0049] Step 121: Determine the data type of each plaintext password in the fused cipher set, and divide the multiple plaintext ciphers in the fused cipher set into multiple different cipher subsets according to the data type.
[0050] After obtaining the user's fused password set, first determine the data type of each plaintext password in the fused cipher set. For example, each plaintext password is composed of one or more of English letters, numbers, and special characters. The English letters, numbers or special characters of the password determine the data type of the plaintext password, wherein the data type includes but not limited to number type, character type, mixed type, etc. Then, according to the data type corresponding to each plaintext password, several plaintext passwords in the fused cipher set are divided into multiple different password subsets, each pa...

The present application provides a weak password analysis method, device, storage medium and electronic equipment. The method includes: obtaining a user's fusion password set, and combining each plaintext password in the fusion password set with common passwords and / or user characteristic data Obtained; use the clustering analysis model to cluster multiple plaintext passwords in the user's fusion password set to obtain multiple clusters, and select at least one target cluster from the multiple clusters; use at least one The encryption algorithm encrypts each plaintext password in each target cluster respectively to obtain a plurality of corresponding first ciphertext passwords; Each second ciphertext password is compared to determine whether the user has set a weak password or not. Compared with the brute force cracking method in the prior art, the present application greatly reduces the amount of analysis data, improves analysis efficiency and recognition accuracy.
Description
technical field [0001] The present application relates to the technical field of information security, in particular, to a weak password analysis method, device, storage medium and electronic equipment. Background technique [0002] With the development of information technology, enterprise software systems and hardware devices continue to increase. Among them, software systems and hardware devices mainly use static passwords to log in. Since users need to set more passwords, most users use related common passwords within the enterprise to set passwords. , These commonly used passwords not only increase the risk of passwords being cracked, but also easily lead to information leakage and attacks on a large number of software systems and hardware devices of the enterprise, causing major economic losses to the enterprise, and even major production accidents of the enterprise. Therefore, effectively identifying whether each user in the enterprise has such a high-risk weak passwo...
