Abstract: The recent advance in secure network coding techniques was reviewed. Firstly, the main idea of network coding was introduced. Then a number of secure network coding protocols were demonstrated to contact different adversaries in communication networks and the design of secure network coding schemes integrated with the characteristics of network coding was highlighted. Furthermore, a brief overview of the relationships among secure network coding, cost criterion and network capacity were presented. Finally, the theory and application prospects for secure network coding were given and analyzed. Considering the intrinsic properties of network coding, to devise simple and efficient secure network coding schemes is an important tendency.
