Due to the severe resource constraints in the Wireless Sensor Networks (WSNs), the security protocols




therein, should be designed to optimize the performance maximally. On the other hand a block cipher and




the mode of operation in which it operates, play a vital role in determining the overall efficiency of a




security protocol. In addition, when an application demands confidentiality and message integrity, the




overall efficiency of a security protocol can be improved by using the Authenticated Encryption (AE)




block cipher mode of operation as compared to the conventional sequential encryption and




authentication. Amongst the AE block cipher modes, the Galois Counter mode (GCM) is the latest




recommended AE mode by the NIST. In this paper, we attempt at evaluating the performance of the GCM




mode in the link layer security protocol for a WSN viz. TinySec and compare it with the default




conventional block cipher modes of operation used therein. To the best of our knowledge ours is the first




experimental evaluation of Galois Counter Mode with Advanced Encryption Standard Cipher at the link




layer security architecture for WSNs.
