Existing security systems for Wireless Sensor Networks are either not able to cover all security requirements or are seriously e ffected by too high communications expenses to enable realistic deployments. We present a new security system for event-driven Wireless Sensor Networks, called PaRSec, that covers all security requirements with adequate expenses. For this purpose, a definition of security based on the state of the art is given. The conformity and performance of the existing systems is analyzed. We introduce a concept that solves the typical problems of the existing systems - namely key management, completeness and expenses. As part of the AVS-Extrem project for distributed event-detection in Wireless Sensor Networks, PaRSec's performance is benchmarked in a lab- and a field-test. The evaluation of the latency, throughput and energy consumptions proves that in spite of the complete coverage of all security requirements PaRSec's expenses are still low enough to warrant a realistic deployment of an event-driven Wireless Sensor Network.
