An Optimal Strong Password Authentication Protocol with USB Sticks

Vikram D

Abstract

Authentication is the process for identify the user authorized or not. The identity contains mainly the username and passwords for verifying the two entities. The authentication information’s are stored in the form encryption in a device which is properly registered in the server. At the time of authentication process perform between user and server the intruder can eves-dropping the communication channel and login into the system by an authorized user. To overcome this optimal strong password authentication (OSPA) protocol uses the multiple hash operation the time of authentication for the users. The server chooses the hash function only at the time of user request for the login process. So the intruder cannot know the information which is transferred at the time of authentication process. The OSPA can improve the authentication process for obtaining mutual communication between user and server. The authentication information will not know to the intruder. So the multiple hash function obtains the secure authentication information process. The OSPA protect information of the user & server and protect from the guessing attack. The guessing attack prevention performs by the server using the multiple hash function & USB Stick.
