Research on the Endogenous Security Technology of Polymorphic Smart Network

Current Internet is confront with some defects such as rigid structure, single IP bearing, and disability in suppressing unknown threats, so it is urgent to change the network structure. The full-dimensional defined polymorphic smart network can provide a possible solution to the development of new network technologies. Polymorphic smart network support full-dimensional definition and multi-modal presentation of addressing and routing, switching mode, interconnection mode, network element, transmission protocol, service properties and so on. One of the cores of polymorphic smart network technology is endogenous security technology. The idea of mimic defense proposed by Academician Wu Jiangxing’s team is to introduce a dynamic heterogeneous redundant architecture (DHRA) into the polymorphic smart network. Based on the DHRA, this paper proposes a ruling algorithm based on safety factor and heterogeneity, and a scheduling method based on execution record and component heterogeneity. Through the experimental analysis, compared with other algorithms, this ruling algorithm can significantly improve the accuracy of the arbiter. And when the scheduling method is introduced, the accuracy is further improved, and the security and reliability of the system are effectively improved.
