Problems and Solutions on Security of Wireless Sensor Network in Facilities on Sports Venues

Security issue of sensor networks is greatly different from that of conventional networks. In this paper, the characteristics analysis of wireless sensor network (WSN) has been carried out firstly, through analysis, the security architecture of sensor networks is proposed, trying to outline a general illustration on this area, and then security defense on the wireless sensor network security issues has been implemented secondly, finally the pairwise keying algorithm has been described and analyzed ,from above all, the ultimate security solution of wireless sensor network has been proposed.
