An Improved Hashing Based Password Security Scheme Using Salting and Differential Masking

In this era of digitization, the foremost requirement is information security which is normally secured by some authentication process. Password security is a major issue for any authenticating process and different researches in past have proposed different techniques like hashing, salting, honeywords to make the process most secured. Here, we propose a new technique which involves hashing, then salting and a crash list generation formed by differential masking process. The crash list for any user is stored in the password file. Any security breach with the password file can lead to login attempts by hacker using one of these passwords from the list. An attempt to log in using any of these crash list words raises an alarm for the application and the application can block that user or address. This process performs a unique hashing algorithm with very low time complexity as most of the steps involved simple binary operations.
