Computing & Information Sciences

Discovering new, innovative methods and research opportunities in solving complex present-day and future computing challenges.

The teaching of introductory computer science can benefit from the use of real-world context to ground the abstract programming concepts. We present the domain of pencil puzzles as a context for a variety of introductory CS topics. Pencil puzzles are puzzles typically found in... READ MORE
Low latency anonymity systems, like Tor and I2P, support private online communications, but offer limited protection against powerful adversaries with widespread eavesdropping capabilities. It is known that general-purpose communications, such as web and file transfer, are difficult to protect in that setting. However, online instant... READ MORE
Recent work has demonstrated that self-propagating worms are a real threat to sensor networks. Since worms can enable an adversary to quickly compromise an entire sensor network, they must be detected and stopped as quickly as possible. To meet this need, we propose a worm... READ MORE
