Key agreement protocol a number of parties involved and communicate over a open public network to generate a common secret key called session key. This paper proposes an efficient password based multiparty Key Agreement Protocol. Security of the protocol is based difficulty of breaking Elliptic Curve Discrete Logarithm Problem and one way hash function. This is resistant against different attack. The security analysis have been discuss and proved in this paper. By reviewing various papers on group key exchange protocol, it is found that not all of them achieve all security requirement and efficiency simultaneously.
