LNT: a logical neighbor tree secure group communication scheme for wireless sensor networks
Secure group communication is a paradigm that primarily designates one-to-many communication security. The
proposed works relevant to secure group communication have predominantly considered the whole network as being
a single group managed by a central powerful node capable of supporting heavy communication, computation and
storage cost. However, a typical Wireless Sensor Network (WSN) may contain several groups, and each one is
maintained by a sensor node (the group controller) with constrained resources. Moreover, the previously proposed
schemes require a multicast routing support to deliver the rekeying messages. Nevertheless, multicast routing can
incur heavy storage and communication overheads in the case of a wireless sensor network. Due to these two major
limitations, we have reckoned it necessary to propose a new secure group communication with a lightweight rekeying
process. Our proposal overcomes the two limitations mentioned above, and can be applied to a homogeneous WSN
with resource-constrained nodes with no need for a multicast routing support. Actually, the analysis and simulation
results have clearly demonstrated that our scheme outperforms the previous well-known solutions
