The wireless sensor network is the self configuring type of network. In these kinds of networks mobile nodes can leave or join the network when they want. In such type of networks many active and passive attacks are possible. To prevent from these active and passive attacks trust relationship between the mobile nodes must be maintained. The trust relationship between the mobile nodes is provided by mutual authentication. ALARM is the protocol for providing trust relationship between the mobile nodes. In this protocol the clocks of the mobile nodes are weakly synchronized by using GPS.
