Traditionally, keys are generated using the hash value of the given image in the image cryptography to boost the security effects. The keys have been sent to the concerned receiver for every new plain image. Sending hash keys is a very time-consuming and inefficient process. To overcome the issue, we have proposed novel image-swapping encryption based on the TetraVex game and publicly hash-sharing algorithm. The proposed scheme consists of two main parts: the first part tackles the key sharing issue, while the second part focuses on developing a unique image encryption method. The proposed approach converts the hash value into the pairs of elliptic curves by the Neal Koblits technique. These pairs are then encrypted using the Diffie Hellman (DH) method before being sent to the authorized party. Moreover, the TetraVex game has been constructed, and the image pixels are swapped using the game to realize …
