For my security class, I chose to author my extended abstract concerning secret group handshakes. Though not intended to be a research paper, it covers the basic aspects of how secret handshakes are done, why they’re useful, and some security weaknesses inherent in the common approaches.
Abstract
“Secret groups, while preserving the anonymity of the members, have a multitude of applications. Discussed here are the fundamentals of a relatively new approach to anonymity called a secret handshake and the key concepts preserving that secrecy. Following an explanation of the mechanics of two and multi-party handshakes, open problems are presented and future research directions are suggested.”

I wrote a paper for my Operating Systems class this recent semester about covert channels.
Abstract
A thirty year-old problem, covert channels continue to plague the security of modern operating systems. These channels are explained and discussion of the subject is motivated. A short evolution of the problem is given as well as several classifications of covert channels. Several methods such as type enumeration, flow analysis, virtualization, and adding noise are discussed and analyzed. Finally, one system is evaluated in context of those methods and future directions into covert channel research are suggested.
