Diffie-Hellman (D-H) key exchange protocol, first published in 1976 is one of the most distinguished and widely used secured key exchange protocols. The protocol makes it possible to exchange a symmetric key between two parties over an unsecured communication channel without pre-agreement of any shared secret. The D-H key exchange protocol however requires a pre-set public parameters P (a large prime) and g a generator of ℤp to be public i.e. known to all users of the system. This paper proposes a key exchange mechanism without any public parameter. Unlike D-H key exchange mechanism our scheme uses encryption to transmit intermediate data during key exchange stage, thus it is non-vulnerable to man-in-the-middle attach.
