A NEW TECHNIQUE OF GENERATING KEY FOR DIFFIE HELLMAN ALGORITHM

Diffie Hellman always remain a very accepted algorithm from the starting when it was created , but with the time it get changes in it to go parallel to the security of the world. So in order to get a better security many had implemented different techniques for generating keys and encrypting data. With the fast progression of using images in many applications, now we are using them for generating keys in Diffie Hellman key exchange algorithm. Since image contains pixel values which are in huge amount for a single image, then we can use them as a particular value to each one of them. During the process of creation of private and public key we are getting then with the help of different functions used as a whole. This will give a secure method of generating keys as some random values. High security is the main motive this paper as other people also used generation of keys with image, but they lack in security in some manner. Now our technique or algorithm will provide a highly secured process of key generation which will almost impossible to brute force it in any manner. If a hacker will try any brute force method then it may take thousands of year to crack it since the value we get after performing functions will give a large value which will be hard to penetrate into security of this algorithm.
