World War, IT security and cryptology systems are getting important day by day. Beside DES and Triple DES of IBM Inc., RCX series of symmetric algorithms and MD5 variant HASH algorithms of RSA Inc. have widely used in cryptology research area. However, recent technology concepts such as faster micrapmcessors, nano-technology and quantum computers make the change inevitable. In the present study, Wavelet Transform method prefening signal processing and image compression areas, is used as data scrambling procedure. The results were compared by parameters such as reliability, algorithm speed.
