08:30 Enhancing Network Security Using 'Learning-from-Signals' and Fractional Fourier Transform Based RF Fingerprints

Abstract - Wireless Access Points (WAP) remain one of the top 10 network security threats. The goal of this proof-of-concept research is to develop a physical layer aware Radio Frequency (RF) air monitoring system to provide a first-line of defense for network security--stopping attackers before they can gain access to critical infrastructure networks through vulnerable WAPs. This paper presents early results on the identification of 802.11a devices using RF Distinct Native Attribute (RF-DNA) fingerprints produced by the Fractional Fourier Transform (FRFT). These fingerprints are input to a Differential Evolution (DE) optimized "Learning from Signals" (LFS) classifier. The results consider WiFi devices under the most challenging conditions of intra-manufacturer classification, i.e., same-manufacturer, same-model, differing only in serial number. Performance of the FRFT RF-DNA fingerprints will be compared to previously published results using Wavelet Domain (WD), Time Domain (TD) and Spectral Domain (SD) fingerprints.

Abstract - In 2001, the JPEO JTRS established the landmark SCA v2.2, formally defining what would become the military communication standard. The SCA specification defined for the first time what would become the basis of military radio terminals and the pillar architecture to support waveform development. The primary objective of this specification was waveform portability enhancement, allowing independent radio manufacturers to migrate waveforms developed by other vendors onto their platforms. However, over time, the inclusion of export-restricted elements in the Security Supplement impeded the standard's international acceptance. In this context, the Wireless Innovation Forum (WInnF, formerly called the SDR Forum) initiated a International Radio Security Service API (IRSSAPI) working group. Over the past year, this group has been devoted to the development of a truly international Security API standard for radio communications with no export restrictions. In addition, this group has and will continue to act as a catalyst between the WInnF development community and government stakeholders. The paper will show the basis upon which the Security Services API will be based, as well as the main drivers for its definition. The paper will conclude with the main achievements and the expected future work.
09:18 A Technical Overview of the International Radio Security Service API

Abstract - The JPEO JTRS established a new paradigm for software definable radios with their release of the Software Communications Architecture (SCA) specification. This specification details requirements and outlines a framework for software based radio platforms. The intentions of this specification are to foster portability of waveform applications between divergent radio platforms. Beyond an initial historical draft, the JTRS program currently has no provisions for a publically available security API that the broader international community can use to develop portable waveforms. Recognizing a lack of an internationally available security API for SCA based radios, the WInnF organization has developed a security API called the International Radio Security Services API (IRSS API) to fill this gap. This paper introduces and presents a technical overview of the major interfaces supporting wideband networking waveform. Primary focus of the paper will center on the establishment of secure networking channels via network security protocols, including the application of asymmetric key management techniques.
