An Efficient Password Security of Multi-Party Key Exchange Protocol Based on ECDLP

摘要

In this paper we have proposed an efficient password security of multiparty Key Exchange Protocol based on Elliptic Curve Discrete Logarithm Problem. Key exchange protocols allow a group of 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, anumber of key exchange protocols have been suggested over the years for a variety of settings.our Protocol is password authentication model, where group member are assumed to hold an individual password rather than a common password. Here we have taken two one-way hash functions to built the level of security high.
