Third-Party Authentication Using Secure-Engine

In this modern era no part of the data is safe and secure. The privacy of the data is being breached every hour by the intruders. Therefore user authentication and access control is very crucial in data storage environment in cloud. Therefore, maintaining the integrity of the data has become a major issue nowadays, to safe guard the data we have introduced a unique network authentication protocol. Our system provides powerful authentication for client-server models by using double encryption. The ticket generated by secure-engine is used for true authentication in the security system. Ticket generated during the process is valid for certain amount of time which is long enough for the hacker to breach, so we introduce the concept of dynamic time stamp, which chooses a specific time window according to the usage of the client. This paper proposes to use Diffie-Hellman key encryption as double encryption to strengthen the security of authentication protocol. To limit the number of sessions through which the data can be accessed, it is restricted to one session per user.
