| Abstract: | Based on the encryption principle of a reversible integer Hash function, a new G function construction is proposed and analyzed. The frequency hopping pattern thus generated has not only good randomicity and uniformity, but also features for easy implementation and encryption key generation easily controlled. The final results of the experiment using this new G function algorithm prove that it has high complexity and strong anti-attack features. |
