Authentication protocol is used for authenticating the two communicating entities in order to build a secure communication channel between them to exchange messages. This authentication is built using exchange of keys. The existing authentication protocol has flaws of mutual authentication and tried to overcome the existing flaw. The paper combines the Otway Rees protocol with a new protocol termed as CHAP (Challenge handshake authentication protocol). It authenticates the communicating entities by using a shared key. Authors also compare symmetric algorithms and choose the best algorithm for encryption.
