6LoWPAN stands for \"IPv6 over Low-power Wireless Personal Area Networks\". Low-power Wireless Personal Area Networks (LoWPANs) are much like Wireless Sensor Networks (WSNs). Both consist of battery-powered and computationally-restricted nodes. 6LoWPAN is a protocol stack for seamlessly integrating 802.15.4- based wireless sensor networks with IPv6 networks. The security of 6LoWPAN widely depends on the 802.15.4 security sub-layer. This sub-layer also supports pairwise keys so as to mitigate node compromises. Currently, the establishment of pairwise keys is however unspecified. Moreover, broadcast keys are shared among multiple nodes, which is not compromise resilient.
