Q. What is Triple Key Management Scheme?
The triple key management mechanism provides optimum security by enabling the use of two pre-deployed keys for each of the WS nodes, and a cluster key that is in-network generated. Here, the "communication mechanism involves a sensor key which is used to encrypt and decrypt data routed to the base station, which is decrypted by each target node and rerouted to the cluster header. In this case, the cluster header communicates with the base station and adds its own ID and the packet load together. An authentication on the MAC packet received at the base is used to verify the integrity of the packet as illustrated in figure below.
