The paper designed and analyzed two secure group key establishment mechanisms for multicasting in WSNs in the context of IoT applications. The key derivations also implicitly authenticate group members, whereas the key can be further used for securing multicast messages. According to the performance evaluations, computation and communication energy consumptions of both protocols are tolerable by the resource-constrained sensor nodes. The security analysis reassures the stronger security features of those protocols proposed compared to reference solutions. Scalability properties of these protocols ensure the support of frequent changes of the multicast group.
研究不足
The paper does not consider the sleeping patterns of the nodes and path losses in the communication links since they are out of the scope of the key objective of this paper. Therefore, it is assumed that the members of the multicast group will eventually receive the initiator requests and the rest of the messages without failures.
