Group-based password intensity assessment method

Abstract

The invention discloses a group-based password intensity assessment method. The method comprises the steps of password assessment preparation, neural network training and group password intensity assessment, wherein the password assessment preparation step comprises the sub-steps of determining group attribute features, constructing a group set according to the attribute features, collecting a password set, cleaning password set data, and finishing password set data preprocessing; the neural network training step comprises the sub-steps of determining a neural network model, and collecting preprocessing results to train a neural network; and the group password intensity assessment step comprises the sub-steps of inputting a password to the trained neural network, and assessing the intensity of the password in a trained group. The intensity of the password in the group is assessed by utilizing the neural network; the neural network is compressed to achieve the plug and play effect; thepassword intensity is timely fed back; a weak password of the group is eliminated to a certain extent; the capability of resisting password guessing attacks by the password is enhanced; and the password security is improved.

Description

technical field [0001] The invention belongs to the technical field of information security, in particular to a group-based password strength evaluation method. Background technique [0002] With the continuous development of Internet technology, the informatization and digitalization of the living environment continue to advance, and network technology has penetrated into all aspects of people's lives. Due to the frequent occurrence of network security issues, people have paid more attention to the security of the network environment. Identity authentication technology has become the most basic and important means of protecting users' personal information security. In identity authentication technology, due to its easy deployment, low cost and simple implementation, text password will still be an important means of identity authentication technology in a short time or even in the future. However, in order to facilitate the user's memory, most of the passwords used by the u...

Problems solved by technology

However, at present, various Internet service providers do not have a unified password evaluation method, resulting in different feedback results for the same password in different environments, which brings confusion to users and leads to security risks for user passwords.

[0003] Due to the ease of memory, the user's password is not completely random or meaningless, and usually uses meaningful characters such as birthdays and names, which reduces the security of passwords

In addition, through the research, it is found that users of different groups may choose characters with group characteristics as passwords due to their potential attributes such as occupation, region, and name, so there are potential password security problems
