Image security is the need of today’s era. The security task is being convoluted as there are a variety of data to secure as different levels of data security is needed based on the data type. Encryption is the maximum expedient approach to guarantee the safety of images over public networks. We have proposed a new public key cryptosystem based on polynomial equation. This approach has been desired because of their resistance to the cryptanalysis attacks. Parameters such as correlation coefficient, entropy, histogram analysis are used for the efficiency of our proposed method. The theoretic and simulation result provides a high quantity of protection. Thus, it is suitable for practical use in secure communication.
