Abstract
Wireless sensor networks WSNs are made up of large groups of nodes that perform distributed monitoring services Since sensor measurements are often sensitive data acquired in hostile environments securing WSN becomes mandatory However WSNs consists of lowend devices and frequently preclude the presence of a centralized security manager Therefore achieving security is even more challenging Stateoftheart proposals rely on 1 attended and centralized security systems or 2 establishing initial keys without taking into account how to efficiently manage rekeying In this paper we present a scalable group key management proposal for unattended WSNs that is designed to reduce the rekeying cost when the group membership changesThis work has been partially supported by the Spanish Comisión Interministerial de Ciencia y Tecnología CICYT with the project P2PSEC TEC200806663C0301 the Spanish Ministerio de Ciencia e Innovación with the CONSOLIDER project ARES CSD200700004 the Spanish Ministerio de Industria Energía y Turismo with the AVANZA funds for ITEA2 project DiCoMa TSI020400201155 and the Generalitat de Catalunya with the grant 2009 SGR1362 to consolidated research groups awarded to the Information Security Group of the Universitat Politècnica de Catalunya
