"A key predistribution-based tag encoding scheme KEPTE" !!!!

We propose a key pre distribution-based tag encoding (KEPTE) scheme to
detect polluted data packets. KEPTE shows competitive performance as follows:
It is computationally efficient because it does not require a large field. All intermediate
nodes and sinks are able to detect pollution attack. All intermediate
nodes and sinks are able to detect tag pollution attack. Random linear network
coding will be executed among the data blocks in the same generation, which is
usually identified by a generation id. So we can perform KEPTE in each generation
as a separate file.www.fu-vision .com
