Implementation of Secure 6LoWPAN Communications for Tactical Wireless Sensor Networks

Naval Research Program ProjectNaval Research Program ArticleTactical wireless sensor networks (WSN) consist of power constrained devices spread throughout a region of interest to provide data extraction in real time. The main challenges to the deployment of tactical WSNs for mission-centric operations are limited nodal energy and information security. In this paper we develop security mechanisms to be implemented on a tactical WSN using the 6LoWPAN protocol for use by the United States Marine Corps (USMC). Specifically, we develop an architectural framework for tactical WSNs by studying security gaps and vulnerabilities within the 6LoWPAN security sublayer which is based on IEEE 802.15.4. We develop a key management scheme that is non-broadcast but that is also feasible in an operational scenario. In addition, we modify the 6LoWPAN packet structure to facilitate the newly developed keying mechanism. The tactical WSN architecture is designed to defend against a variety of network attacks that can potentially occur. Simulations will be conducted via MATLAB to show the effectiveness of the developed keying and communication mechanisms.Naval Research ProgramMarine Corps Systems Command (MCSC) in Quantico, VA, Grant Number NPS-N16-M296-BMarine Corps Systems Command (MCSC) in Quantico, VA, Grant Number NPS-N16-M296-

Implementation of secure 6LoWPAN communications for tactical wireless sensor networks

Naval Research Program ProjectThe ability to securely disseminate data in a timely manner is critical to military missions within a hostile environment. Tactical wireless sensor networks (WSN) consist of power-constrained devices spread throughout a region-of-interest to provide data extraction in real time. In this thesis, we develop cyber security mechanisms to be implemented on a tactical WSN using the 6LoWPAN protocol for use by the United States Marine Corps (USMC). Specifically, we develop an architectural framework for tactical WSNs by studying cyber security gaps and vulnerabilities within the 6LoWPAN security sublayer, which is based on the IEEE 802.15.4 standard. We develop a key management scheme and a centralized routing mechanism that is non-broadcast but feasible in an operational scenario. In addition, we modify the 6LoWPAN enabled IEEE 802.15.4 frame structure to facilitate the newly developed keying and centralized routing mechanisms. Methods to aid in deployment planning are also discussed. The tactical WSN architecture was tested against a variety of well-known network attacks. The attacks simulated were spoofing, man-in-the-middle, and denial-of-service. Through MATLAB simulations, we showed the effectiveness and efficiency of the developed cyber security mechanisms to provide integrity and reliability to a deployed tactical WSN.http://archive.org/details/implementationof1094550526NPS-N16-M296-BOutstanding ThesisLieutenant, United States NavyApproved for public release; distribution is unlimited
