Abstract

This paper presents a method for encrypting messages, which uses for this operation an image or a part of an image as an encryption/decryption key. The need to encrypt messages for protecting their content knew an increase from the apparition of Internet and electronic transactions. The great number of messages that flows in a computer network and over the Internet is requiring very fast encrypt/decrypt processes for assuring real-time secured communications. Complex algorithms used in present for encrypting/decrypting messages use complex keys and complex encrypt/decrypt functions that need an increased computer power for real-time applications (media).
