SenSec: A Scalable and Accurate Framework for Wireless Sensor Network Security Evaluation

Developing secure wireless sensor networks (WSNs) is a complex process that involves careful design of attack test cases and security countermeasures, as well as meaningful evaluation of the impact of the attack and performance of the countermeasure. In this paper, we present the design and implementation of Sen Sec, a scalable framework that facilitates the development and evaluation of secure WSNs, protocols, and applications. We also demonstrate key benefits of Sen Sec: (1) it allows security evaluation of real sensor applications, (2) it can be easily extended to any real application simulator, (3) it provides a modular structure for defining attack cases and supports extensibility to a broad set of attacks, (4) it supports automatic generation of sophisticated and previously unconsidered attack cases, and (5) it facilitates the analysis and identification of vulnerabilities in security systems and a quantitative evaluation of the impact of attacks and countermeasures in WSNs.
