Research on Confidentiality of Vector Map Data Based on Logistic Mapping

摘要：

In order to ensure the security of Web Geographic Information System in network transmission,the vector map data can be encrypted in the way of byte by byte using the chaos system to design encryption arithmetic.In this way of encryption,it should firstly make sure the parameter of Logistic mapping,secondly the logistic mapping should be the key stream generator,which would be design to convert block cipher Data Encryption Standard into sequential cipher,finally the result of encryption should be real-time and key stream longness of plaintext and cipher text would be the same.In this way the impression of encryption would be more secure and efficient.The experiment showed that this arithmetic had less error code diffusibility and efficiency was well.
