Abstract: A sensor network is composed of large number of sensor nodes. Each sensor needs to securely communicate with the adjacent sensors in the network. To provide security between every pair of adjacent sensor each sensor in a network needs to store ‘n -1’symmetric keys But The storage requirement of this keying protocol is very complex. In this paper, we propose a new keying protocol which reduces the number of keys to be stored in each sensor. we present a fully secure keying protocol here each sensor needs to store (n+1)/2 keys, which is less than the n-1 keys and symmetric keys are used to encrypt and decrypt the exchanged data for secure communication. At least (n-1)/2 keys are required to store in each sensor to secure an entire keying protocol. This new secure keying protocol is very secure against impersonation, eavesdropping and collision attacks.
