Enhanced Authentication Scheme using Password Integrated Challenge Response Protocol

Authentication is a process by which both the sender and receiver check and identify the validcommunicative partners prior to initialization of message exchange. Authentication is a security module which is defined at the time of starting of communication between the two communicating entities such as client and server due to the unlimited amount of insecure and malicious intruders it becomes significant to protect the network communication. The protocols are used here for initializing the valid keys and passwords for communicating with the devices. Here we are proposing a new and more secured authentication scheme based on unique identification of every pair of client and server which have entered communication on a global network. This method enhances the present security scenario by diminishing the replay, modification attacks as well as server eavesdropping. This method also enhances the efficiency, integrity, reliability and security in authentication process.
