In this work we present a protocol for key establishment in wireless sensor networks. Our protocol is designed so that it supports security of data with various sensitivity levels. In particular, the protocol allows the establishment of a key that can be used for communication with the base station, pairwise keys that can be used to communicate with immediate neighbors and keys that allow for secure in-network processing. This last form of operation includes both secure aggregation and dissemination processing and is beneficial to sensor networks as it saves energy and increases network lifetime. Our proposed protocol is simple and scalable and exhibits resiliency against node capture and replication as keys are localized. Furthermore, our protocol allows for incremental addition of new nodes and revocation of compromised ones, while at the same time offers efficiency in terms of computation, communication and storage overhead.
