Digital Signature and Key Agreement

Krishna Kant, Fahim Iqbal, Md Irshad Alam

Abstract


Diffie Hellman key exchange protocol is the most commonly  used protocol. This protocol is used to exchange keys in a network. But it has bit m to exchange keys over a network but it has some drawbacks.  This is the first proposed algorithm through which parties can exchange information without knowing each other. This algorithm permits exchange even over a insecure networks. Hellman algorithm was introduced  by Martin Hellman and Whitfield Diffie in 1976. It is useful over a large number of authenticated protocols. Moreover,  it works on transport layers too. In this research efforts are being  made to declare new agreement protocol based on key confirmation and  Diffie Hellman algorithm as well. This work also ensures the  digital signature standard (DSS) with the help of Diffie-Hellman key exchange protocol by making use of two integers randomly. This protocol also performs on the elliptic curve cryptography in asymmetric encryption.
