A Secure RSA-Based Image Encryption Method

Modern world moves around data communication, and its security is a key issue nowadays. It is very unsafe to transmit images over insecure wireless communication channels. In this paper, a secure and reliable image encryption method using RSA is proposed. RSA is one of the most trusted and reliable public key encryption algorithms used over the years. We use the strongness of RSA for transmitting images over insecure channels and provide an easy implementation technique. The proposed method is capable to encrypt any image using RSA parameters (selected by user). Initially, a public–private key pair is generated, and then, the image (which is to be transmitted) is encrypted by the public key where as private key is used for the decryption process. The most important point associated with the proposed method is that it gives freedom to users to select their own parameters making the method convenient, customized, and robust and provides high level of security.
