By carefully measuring the amount of time required to perform private key operations, attackers may be able to find fixed Diffie-Hellman exponents, factor RSA keys, and break other cryptosystems.Against a vulnerable system, the attack is computationally inexpensive and often requires only known ciphertext. Actual systems are potentially at risk, including cryptographic tokens, network-based cryptosystems, and other applications where attackers can make reasonably accurate timing measurements. Techniques for preventing the attack for RSA and Dif ....etc

ns2 coding for the implementation of eliptic curve diffie hellman key exchange between nodes in manet

Abstract

Elliptic curve Diffie Hellman (ECDH) is an anonymous key agreement protocol that allows two parties, each having an elliptic curve public private key pair, to establish a shared secret over an insecure channel. This shared secret may be directly used as a key, or to derive another key which can then be used to encrypt subsequent communications using a symmetric key cipher. It is a variant of the Diffie Hellman protocol us ....etc

implementation code in matlab for diffie hellman

Introduction

The article is devoted to the development of the library that implements the Diffie Hellman cryptographic algorithm of key exchange. The library appeared as a result of the necessity to use the Diffie Hellman algorithm without the involvement of any third-party libraries.

Description of the Algorithm

Diffie Hellman algorithm is an algorithm that allows two parties to get the shared secret key using the communication channel, which is not protected from the interception but is ....etc
