Keywords:
Elliptic Curves Diffie–Hellman, Elliptic Curve Discrete Logarithm Problem, Image EncryptionAbstract
Sharing sensitive photographs across unprotected networks puts you at risk of theft and attack. When it comes to protecting images against attacks, encryption techniques are the best options. Cryptography is necessary in order to send photos securely. The key that is used for encryption and decryption plays a significant role in a cryptosystem's strength. Performing a brute force attack is challenging due to the key size. The complexity of the algorithm also rises, as a result, requiring more computing power. The same level of security can be achieved with smaller key sizes using implemented cryptosystems based on elliptic curves. This paper presented two image encryption cryptographic techniques based on Elliptic Curve Diffie–Hellman Key Exchange and applied them to various pictures. The proposed models were put to the test, where the MSE, PSNR and UACI were calculated to evaluate the efficiency of the proposed techniques
