With the extensively applying of Wireless Sensor Networks (WSN), its' security drew more and more attention. In all the security issues in WSN, session key is fundamental one with great challenge. Due to the constraints of limited hardware resources and computational capabilities, use asymmetric encryption mechanisms in session key are not suitable for WSN. And there are usually a puzzle for existing symmetric encryption mechanisms that they produced heavy communication cost. In this paper, we presented a session key transmission scheme based on an algorithm of Data Partitioning with Coding, named DPC. By using of non-perfect secret sharing, we optimized the communication costs significantly and keep the security in high level. The analysis and simulations prove that our scheme has good performance.
