HAWCS™ JTRS Letter of Support " The High Assurance Wireless Computing System (HAWCS™) is a patent-pending security architecture for wireless mobile terminals and software defined radios, defending platform integrity from network "hacking" attacks. HAWCS™ was designed to address JTRS CP 295, "Exposed Black Side". HAWCS™ has a letter of support from the Director, JTRS Network Enterprise Domain, and Orange PCS (a division of France Telecom).

HAWCS™ Orange PCS Letter of Support: The High Assurance Wireless Computing System (HAWCS™) has received a letter of support from one of Europe's largest wireless networks, a subsidiary of France Telecom.

HAWCS™ Phase II SBIR Breifing: SBIR Topic AF03-098 Phase II develops a prototype laptop computer with a functional prototype JTRS SCA compatible HAWCS™ modem. The HAWCS™ architecture employs MILS operating system and ORB, and a commercially available trusted computing module (TCM) for protecting wireless mobile devices and software defined radios (SDR) from network attacks by wireless and Internet hackers. For SCA compliant applications, HAWCS™ is used on the Red and Black sides, and the prototype employs a Advanced INFOSEC Machine (AIM) development card, algorithms and board support package supplied by GD C4 Systems. HAWCS™ has been endorsed by the JTRS Network Enterprise Domain (NED) director as a possible means of addressing JTRS CP295, 'Exposed Black Side' during Phase III.

Updated System Threat and Requirements Analysis: During SDR 04, we provided the results of a case study of the effect the download of a waveform with a weak security design, such as IEEE 802.11 Wireless Fidelity (WIFI), into a software defined radio (SDR). Wirelessly networked computers, interfacing with the Internet via WIFI, GSM, and other vulnerable waveforms, are becoming increasingly prevalent, and provide a useful case study highlighting the potential dangers posed by hackers to networks of software defined radios. Within the past year, our report on the threats posed by WIFI on SDR has had wide impact on the SDR security community. Supported in part by a US Air Force Small Business Innovation Research (SBIR) contracts, we have conducted a system threat and requirements (STAR) analysis for software defined radios and wireless computers employing WIFI, commercial waveforms, and other waveforms. The study concludes that numerous commercial wireless networks, and other wireless networks with certain characteristics, are subject to blended attack methods combining coordinated attacks on the radio and computer interfaces. Building on the results of last year s paper, we survey various approaches which may help to mitigate the threat posed by blended hacking attacks on software defined radio terminals and networks. We also recommend a security architecture approach for consideration by the SDRF.
