Securing Digital Holographic Complex Information using Double Random Phase Fresnel Plane Encoding and Diffie-Hellman Key Exchange

Diffie-Hellman type key exchange protocols based on isogenies

‎In this paper‎, ‎we propose some Diffie-Hellman type key exchange protocols using isogenies of elliptic curves‎. ‎The first method which uses the endomorphism ring of an ordinary elliptic curve $ E $‎, ‎is a straightforward generalization of elliptic curve Diffie-Hellman key exchange‎. ‎The method uses commutativity of the endomorphism ring $ End(E) $‎. ‎Then using dual isogenies‎, ‎we propose...

A Diffie-Hellman Key Exchange Protocol Without Random Oracles

Authenticated Diffie-Hellman Key Exchange Algorithm

The ability to distribute cryptographic keys has been a challenge for centuries. The Diffie-Hellman was the first practical solution to the problem .However, if the key exchange takes place in certain mathematical environments, the key exchange become vulnerable to a specific Man-inMiddle attack, first observed by Vanstone. This paper is an effort to solve a serious problem in Diffie-Hellman ke...

Provably Secure Password-Authenticated Key Exchange Using Diffie-Hellman

When designing password-authenticated key exchange protocols (as opposed to key exchange protocols authenticated using cryptographically secure keys), one must not allow any information to be leaked that would allow verification of the password (a weak shared key), since an attacker who obtains this information may be able to run an off-line dictionary attack to determine the correct password. ...

A Secure Wireless Communication Protocol using Diffie - Hellman Key Exchange

In 1976, Diffie and Hellman in their path breaking paper [5] proposed a two party key agreement protocol based on finite field. Diffie – Hellman Key Exchange Protocol [DH protocol] has unique importance in two party wireless communication scenarios. After this protocol several protocols have been proposed bases on DH protocol but the Man in the middle attack raises a serious security concern on...
