Abstract

Authenticated computer system users are only authorized to access certain data within the system. In the future, wireless sensor networks (WSNs) will need to restrict access to data as well. To date, WSN security has largely been based on encryption and authentication schemes. The WSN Authorization Specification Language (WASL) is a mechanism-independent composable WSN policy language that can specify arbitrary and composable security policies that are able to span and integrate multiple WSN policies. Using WASL, a multi-level security policy for a 1000 node network requires only 60bytes of memory per node.
