Design and analysis of streaming media encryption system based on Logistic chaotic mapping

Since the volume of streaming media data is so huge, it is hard to solve security and real-time problems at the same time by implementing traditional encryption arithmetic. In order to meet these two requirements, combined with Public Key cryptographic algorithm RSA, this paper designs a new encryption system (RSA-DLCM) by taking chaotic system as the base and remedying the defects of chaotic system. According to the test, the new encryption system meets these two requirements very well.
