Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0026] The invention provides a password traversal device based on a generative confrontational network, including a rule dynamic generation engine module, a rule history database and a fast deduplication engine module, a password rule conversion and deduplication judgment engine module, and a verification password and cycle control module .

[0027] The rule dynamic generation engine module adopts the trained confrontational network model to dynamically generate password rules, such as figure 2 , the rule dynamic generation engine module includes: a rule encoder, a confrontation generator, a rule decoder, and a decoding table. Both the rule encoder and the rule decoder encode the meta-operations of the password transformation rule into a 2-digit hexadecimal code in a unified order, and meet the input specification of the generative confront...

Abstract

The invention provides a password traversal device and method based on a generative adversarial network, and the method comprises the steps: dynamically generating a high-quality password conversion rule through employing the generative adversarial network technology after the password conversion rule is coded, combining the obtained rule with a password dictionary, and deriving a test password for password recovery; according to the password traversal method provided by the invention, the password set with higher possibility can be preferentially verified, and the average time required by password recovery is shortened. The generative adversarial network is applied to the password traversal device capable of dynamically generating the rules for the first time, and the problem that password transformation rules in the password recovery field are scarce can be solved.

Description

technical field [0001] The invention relates to the technical field of password recovery, in particular to a password traversal device and method based on a generative confrontation network. Background technique [0002] The advent of the Internet era has made the flow of data faster, and data transmission and sharing can be seen everywhere. The ensuing question is how to protect confidential data. The use of passwords to protect personal information is a common and convenient method. Password recovery refers to the process of recovering the password plaintext from the ciphertext. Password recovery has a wide range of applications. Password recovery technology plays a big role in academic, civil, and national defense, and researches on password recovery emerge in endlessly. [0003] Traditional password recovery methods include exhaustion, dictionaries, etc. Exhaustive is the literal meaning. It is a very simple method to try to crack passwords one by one by citing all ...
