The emergence of wireless networking as well as the development in embedded systems and technologies have given birth to application specific networks called wireless sensor networks WSNs, their flexibility, facility of use and deployment as well as their low cost give them an increasing field of applications. Usually sensors are limited in capacities deployed in a hostile and unpredictable environment, making the security of these networks a challenging task. In this paper we are going to present a key management scheme in which the base station play the role of the secure third party responsible of distributing key and managing security in the network, two versions of this scheme are presented the first one for flat networks and the second one for hierarchical networks in which the cluster head play the key role in all key agreement with the base station.
