Secure Digital Image Transmission Based On Rsaes-Oaep Asymmetric Cryptosystem

Abstract

Today, with the growth of technology, security is an important issue in communication. In many application, the transmission of data (massage, image and so on) is needed to provide security against from prevent unauthorized users. Cryptography is a technique that provides the secure communication. The two widely accepted and used cryptographic methods are symmetric and asymmetric. There are so many different techniques should be used to protect confidential image data from unauthorized access. This system provides secure image transmission between sender and receiver. This system uses Optimal Asymmetric Encryption Padding (OAEP) with RSA encryption algorithm to provide security during transmission. Only public key cryptography is focused here. Public-key cryptographic algorithm relies on one key for encryption and a different but related key for decryption..  .
