A Encryption Based on Chaotic Map

In order to increase the security of Chaos -based Encryption Algorithm while better anti -differential attack,proposed that encryption sequences carry on the confusion and the proliferation with Joseph Transform, and it can change the number of iteration used express feedback, enables the sequence to enhance anti-breaks after the Logistic mapping encryption. Results showed that the encryption algorithm has good strength of encryption ; contrast to Chaotic Encryption Algorithm which simple based on Logistic Systems , the algorithm has good operational efficiency, solved the low-dimensional Chaotic Encryption Algorithm which lack of confidentiality .
