In this paper the authors have proposed an efficient password security of three-party key exchange protocol based on elliptic curve discrete logarithm problem. Key exchange protocols allow two parties communicating over a public network to establish a common secret key called session key. Due to their significance by in building a secure communication channel, a number of key exchange protocols have been suggested over the years for a variety of settings. Here, they have taken two one-way hash functions to build the level of security high.
