Abstract :
In this paper, we propose a new algorithm to compute the strength of passwords based on two measurements, mainly: password entropy and password quality. The passwords considered by the algorithm consist of eight characters alpha numeric with special characters. For such passwords, the analysis phase identified the low/high entropy patterns and low/high quality passwords. The analysis yields two rules: high entropy passwords are also high quality passwords, and low quality passwords are low entropy passwords.
