This paper applies a recently introduced general analytic framework for spectrally modulated and spectrally encoded (SMSE) signals to carrier interferometry (CI) signals. The SMSE framework mathematically incorporates the waveform adaptivity and diversity found in SMSE signals. Future fourth generation (4G) radios are likely to operate using cognitive(More)
Malicious insiders represent one of the most difficult categories of threats an organization must consider when mitigating operational risk. Insiders by definition possess elevated privileges; have knowledge about control measures; and may be able to bypass security measures designed to prevent, detect, or react to unauthorized access. In this paper, we(More)
In this article, we provide a brief history of the Cyber Defense Exercise (CDX), describe Air Force Institute of Technology (AFIT's) participation in it, and explain how the experience shaped the information-assurance curriculum and course format at AFIT. The CDX is an annual competition designed to give students the opportunity to learn and demonstrate(More)
Authenticated computer system users are only authorized to access certain data within the system. In the future, wireless sensor networks (WSNs) will need to restrict access to data as well. To date, WSN security has largely been based on encryption and authentication schemes. The WSN Authorization Specification Language (WASL) is a mechanism-independent(More)
This paper examines the theory, application, and results for a Reputation-Based Internet Protocol Security (RIPsec) framework that provides security for a Mobile Ad-hoc Network (MANET) operating in a hostile environment. While there has been significant research in MANET security, the research has tended to address subsets of the overall security challenge.(More)
This paper describes how the curriculum and course format at the Air Force Institute of Technology (AFIT) has evolved based on our experience with the highly-successful Cyber Defense Exercise (CDX) sponsored by the National Security Agency (NSA). Using industry-standard hardware and software, AFIT graduate students designed, built, and operated a robust(More)
