The Study Of Chaotic Synchronization Encryption For Image And Document Data

With the consistently increasing development of the information society, the traditional data encryption techniques are not able to meet the demand caused by the network security. It is an increasingly hot topic to find some effective methods to enhance the ability of security of the cryptosystem. Based on reading a lot of domestic and overseas reference papers, a novel CPRNG system integrated the traditional encryption mechanism is proposed. And a data encryption approach making use of the above CPRNG system to chaos synchronization communication is proposed. Theoretical analysis and test results demonstrate that the advantages of the cryptosystem are its higher level of security and synchronization. Then the software on the base of the above scheme is programmed. It realizes encryption communication between two computers and proves the feasibility of the scheme. In addition, programming this software is still a helpful attempt towards the real utility of chaos encryption techniques.
