Now a day's data security is one of key issue in information security whether it is image, audio, text etc. We are sharing image files for many causes like identity information, medical diagnosis, and study on space related issues so while we do transfer images there should be some defensive security mechanism in order to stand against vulnerably attacks on image data. There exists various techniques in cryptography for encryption of images. In this paper we studied various image encryption methods and proposed a more secured Encryption with incorporating RSA algorithm in Password key generation and we have passed same key in consecutive steps of bit rotation, extended hill cipher, modified vernam cipher, modified MSA algorithm in order to improve security of password key as well as Image encryption method.
