摘要：This study proposes a pre-deployment key management scheme that requires a few memory capacities and CPU computations to address secure data transmissions in Wireless Sensor Networks (WSNs). The proposed scheme exploits threshold key management mechanisms by Lagrange Interpolation polynomial generating a key set for sensor nodes, and uses symmetric and irreversible cryptography schemes to encrypt transmitted data by the generated keys with Message Authentication Code (MAC). The sensor nodes merely have to aggregate and encrypt received data without complicated cryptography operations. The proposed approach can achieve rapid and efficient secure data transmissions with low communications, and is proper to be implemented on large-scale sensor networks.
