Password Security Scheme Based on a Honeywords Generation through Hashiing Key and Salting Process

The concept of authentication has evolved in the recent past from simple password based authentication to face recognition, voice recognition and biometric based authentication and so on. But, even after all these various evolutions, password based authentication remains the most widely used method. So, password protection schemes become very important in such cases. This has been a man area of research ever since the inception of word “Authentication�. The researchers, in recent past, have deployed different techniques based on salting, hashing, quantum cryptography and split key methods. The base research by Binoj Koshy [4] describes a salting based hashing process called Chameleon Salting Hashing where he successfully implemented a password security scheme to prevent various attacks. In this paper, we propose an advanced hashing technique combined with salting to improve the security of passwords even though the intruder gets an access to the database. The hashing technique is based on some simple bit conversion methods making it highly efficient in terms of time consumption. The method involves creation of a blacklist as a result of many hashing processes conducted on the input password. Blacklist also known as honeywords list. Each hashing process is based on a different hashing key. The hashing key defines the sequence of actions defined in the hashing process, that take place on the input password. The base research had a major drawback in that it could not prevent brute force attack and also the salting based hashed technique was complicated and the time complexity was high for this. The proposed methodology has far lesser time complexity because it is based on simple bit operations in a 5 step process. The final results shown both numerically and graphically clearly demonstrate the efficiency of proposed technique against base methodology.
