Abstract
Proposes pictureencryption algorithm based on the double unidimensional chaos system.This algorithm uses the double unidimensional chaos system to carry onthe substitution and the replacement transformation to the picture,uses the double chaos system to expand the key space,and increased the key complexity;the substitution and set gathers enhanced theencryption security.the fruit indicates that,thealgorithm calculates speed quick,scrambled text distributedcharacteristic good,the scrambled text dense is sensitive,the bright this algorithm had the high security.
