Secure network coding from secure proof of retrievability

Dear editor, Compared with the traditional storing-and-forwarding rout-ing mechanism,network coding has become a more attrac-tive paradigm because it has been proven capable of achiev-ing maximized throughput,enhanced robustness,and lower energy consumption for communication networks[1].Un-fortunately,this paradigm is highly susceptible to pollution attack[2].More specifically,if a packet is modified illegally(i.e.,polluted packet),then this modification may quickly spread to the whole network because the intermediate node encodes all received packets including the polluted one[3].Therefore,it is critical for the intermediate and terminal nodes to check whether a data packet is polluted,which is also the target of secure network coding (NC) scheme[4].
