IPv6 over Low power Wireless Personal Area Network (6LoWPAN) has emerged as a promising technology to realize ambient intelligence under the vision of the Internet of Things. Under most circumstances, it is imperative that security be addressed from bootstrapping to data transmission. In this paper, the authors propose a secure bootstrapping scheme that includes mutual authentication and trust evaluation to provide the first security measure for 6LoWPAN. The scheme is based on multi-hop cluster-tree hierarchical topology in which pair wise keys between neighboring nodes and trust paths to the Base Station (BS) are established at the same time.
