Wireless Sensor Network (WSN) is a noticeable subject currently. There are many WSN applications including military control and environmental monitoring. In these applications, the security of data transmission is an important issue. Because sensor nodes are resource limited and they do not have fixed structure model, there needs an efficiently key distribution and management mechanisms to achieve secure communication. This paper proposes a scheme which uses an implicit security technique to distribute the encrypted key. Because most of operations are computed by the base station, this scheme can extend survival time of the network and it is very appropriate for WSN.
