A new technique for Diffie-hillman key exchange protocol security using random image generation

Abstract

The rapid development of technology by using the internet as a medium to transfer many types of data has led to the appearance of new problems, such as intrusion, hacking and other problems and providing the security for the progress using these algorithms. The Diffie-hillman algorithm is one of the key exchange protocols that used for the security of information, but by the passing time, the change of security progress led to the occurrence of many problems due to the using Diffie-Hellman protocol in key exchange such as Man-in-the-Middle attack and Discrete logarithm attack. So, to solve these problems and to obtain better security, it needs to generate a random colour image(NxN) for each encryption, then uses an image generated to extract keys by applying the XOR function.
