Abstract: In allusion to the bugs of some chaotic cryptography that the recognize is easy to recognize and the sequence’s distributing is asymmetry,a new data cryptology is brought forward which uses the Arnold cat map pretreatment then XOR the uniform composite choatic sequence.The encrypted effect and the capability of resisting to the statistical attack and system recognition  attack is analyzed.

Key words: uniform composite choatic-sequence, image cryptography, statistical analysis
