encryp ti on algorithm based on unified chaotic system and general cat map s was p r oposed . Firstly, tricol or scrambling
transformati on was realized respectively in s pace domain by using the general cat map s . Then the three chaotic sequences of
unified chaotic system were adop ted t o realize the tricol or Substituti on transformati on p ixel by p ixel . The results demonstrate
that the algorithm has good p roperties of confusi on and diffusi on . The key space is large enough t o resist the brute2 force attack .
For the encryp ted i mage the distributi on of p ixel2 values has a random2like behavi or and the values of adjacent p ixels satisfy
zero correlati on, showing that the p r oposed scheme is of high security .
