Information flow restructuring anonymous communication mechanism based on network coding
基于网络编码的信息流重构匿名通信机制

The existing communication mechanism based on PKI is difficult to apply to a distributed environment with no trustworthy center. This paper proposed a new kind of the anonymous communication mechanism NCBACM which based on the network coding technology. NCBACM proposed that every piece was coded by the random coding coefficient and also chopping the path construction information and data messages into slices, and then coded by the random coding coefficient .Scattering the symbols on the different paths could also make sure the anonymity of the information transmitted between the nodes and also make the anonymous paths be set up without encryption and decryption. Theoretical analysis and simulation results show that compared with only depending on the source node encode mechanism, this mechanism has increased the difficulty of the data message analysis ,and significantly improve the security of the anonymous system.
