Abstract
In this work, a novel stream encryption technique is suggested. The encryption technique is intended to encrypt images in real-time. The paper describes the novel technique at a high level, then it shows details about its hardware implementation. Multiple tests are performed to show the strength of the technique including: key space and sensitivity, statistical analysis of encrypted images such as entropy and histogram, and correlation between the pixels of the encrypted image. All these tests show that the novel technique is at the same level of RC4 the current industry standard of stream encryption. The novel technique also offers a very interesting characteristic that makes it very strong against plain-text attacks. Using the same password and original message but encrypting at different times will generate two completely different ciphered messages, and both ciphered messages will be decrypted correctly to generate the original message. Such property is similar to what tweakable ciphers offer in block cipher techniques but is not available in any steam encryption technique that we are aware of including the industry standard.
