Neural Network Techniques for Proactive Password Checking
This paper deals with the access control problem. The authors assume that valuable resources need to be protected against unauthorized users and that, to this aim, a password-based access control scheme is employed. Such an abstract scenario captures many applicative settings. The issue they focus their attention on is the following: password-based schemes provide a certain level of security as long as users choose good passwords, i.e., passwords that are hard to guess in a reasonable amount of time. In order to force the users to make good choices, a proactive password checker can be implemented as a sub-module of the access control scheme.
