A Novel Method of Generating (Stream Cipher) Keys forSecure Communication
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 1
Abstract
Abstract: Security is an important part of computer science that deals with the protection of importantinformation from access, change or modified, and delete, so there are many ways to improve the security ofinformation like cryptography, steganography, biometrics, passwords, barcode….. However most of thesemethods are considered keys required.These keys are used to implement the changing of the information forsecure style purpose. For that reason, generating and keeping these keys is a major part of the appropriatesecurity system. Moreover, sending the key to the wanted person in unsacred channel is a widely weakness partfor any system. The proposed system is a novel method for generating a secret unique key from an image. Agenerating process is applied by discovering the essential colors in the image and constructing a table values forthese essential colors , after that a suitable threshold is used to considered these values are (0, 1) bits which willbe used as stream bits key.
