Abstract: A common problem with systems that use passwords for authentication is that users choose weak passwords. Weak passwords are passwords that are easy to guess, simple to derive, or likely to be found in a dictionary attack. Thus, the choice of weak passwords may lead to a compromised system. Methods exist to prevent users from selecting and using weak passwords. One common method is to compare user choices against a list of unacceptable words. The problem with this approach is the amount of space ... (Update)
