Image Position Scrambling Algorithm Based on Uniform Distribution

摘要：

In order to improve the security of the image transmission in Internet, some typical methods can change the pixel positions such as Arnold cat map and Hilbert transformation. But their shortcomings of inherent periodicity and nonuniform scrambling may bring great unsafety to encryption system. Based on the reason, a uniform distribution algorithm produced, which makes any small section of original image may uniform distribute in whole encrypted image. The simulation experiments show that the method has some merits of anti-cut attack, key sensitive and quick encryption speed.
