About this title

Synopsis

An expected requirement of wireless sensor networks (WSN) is the support of a vast number of users while permitting limited access privileges. While WSN nodes have severe resource constraints, WSNs will need to restrict access to data, enforcing security policies to protect data within WSNs. To date, WSN security has largely been based on encryption and authentication schemes. WSN Authorization Specification Language (WASL) is specified and implemented using tools coded in JavaTM. WASL is a mechanism-independent policy language that can specify arbitrary, composable security policies. The construction, hybridization, and composition of well-known security models is demonstrated and shown to preserve security while providing for modifications to permit inter-network accesses with no more impact on the WSN nodes than any other policy update. Using WASL and a naive data compression scheme, a multi-level security policy for a 1000-node network requires 66 bytes of memory per node. This can reasonably be distributed throughout a WSN. The compilation of a variety of policy compositions are shown to be feasible using a notebook-class computer like that expected to be performing typical WSN management responsibilities.
