- Group-Aware Stream Filtering for Bandwidth-Efficient Data Dissemination
- This paper is concerned with disseminating high-volume data streams to many simultaneous applications over a low-bandwidth wireless mesh network. For bandwidth efficiency, they propose a group-aware stream filtering approach, used in conjunction with multicasting, that exploits two overlooked, yet important, properties of these applications, many applications can tolerate some degree...

- Combating Spam and Denial-of-Service Attacks With Trusted Puzzle Solvers
- Cryptographic puzzles can be used to mitigate spam and Denial-of-Service DoS attacks, as well as to implement timed-release cryptography. However, existing crypto puzzles are impractical because: solving them wastes computing resources and/or human time, the time it takes to solve them can vary dramatically across computing platforms, and/or applications become...

- Attribution and Aggregation of Network Flows for Security Analysis
- This paper describes a network flow analyzer that is capable of attribution and aggregation of different flows into single activity events for the purposes of identifying suspicious and illegitimate behaviors. Flows are correlated with security events using the Process Query System PQS infrastructure. This paper shows results from initial experiments...

- Online Behavioral Analysis and Modeling Methodology (OBAMM)
- This paper introduces a novel method of tracking user computer behavior to create highly granular profiles of usage patterns. These profiles, then, are used to detect deviations in a users' online behavior, detecting intrusions, malicious insiders, misallocation of resources, and out-of-band business processes. Successful detection of these behaviors significantly reduces...

- AutoPKI: A PKI Resources Discovery System?
- The central goal of Public Key Infrastructure PKI is to enable trust judgments between distributed users. Although certificates play a central role in making such judgments, a PKI's users need more than just knowledge of certificates. Minimally, a relying party must able to locate critical parameters such the certificate repositories...

- Project Management Methodology in Human Resource Management
- The concept of project management methodology can be leveraged to add value to an institution's strategic initiatives. This paper provides an overview of project management methodology, when it should be used, and how it can add value to human resources management. The authors also explore project management's role in HR...

- Is this Rembrandt a real one?
- About a year ago, I told you about how computer scientists from Dartmouth college were investigating digital images. But they're also interested in old paintings authentication, as reports Wired Magazine in The Rembrandt Code. Mathematicians are using high-resolution digital cameras and computers to examine old paintings and evaluate their authenticity....

- A Degree in Endpoint Security and Management
- Founded in 1769, Dartmouth College is a member of the prestigious Ivy League. Dartmouth's high-speed network connects all dormitory rooms, administrative offices, and academic buildings on campus and off campus. All Dartmouth undergraduates own a PC or laptop computer, contributing to the more than 9,000 PCs used across the campus...

- Online Power-Aware Routing in Wireless Ad-hoc Networks
- This paper discusses online power-aware routing in large wireless ad-hoc networks for applications where the message sequence is not known. The paper seeks to optimize the lifetime of the network. The paper shows that online power-aware routing does not have a constant competitive ratio to the off-line optimal algorithm. This...

- Hierarchical Power-Aware Routing in Sensor Networks
- This paper discusses online power-aware routing in large sensor networks. The authors seek to optimize the lifetime of the network. The paper develops an approximation algorithm called max-min zPmin that has a good empirical competitive ratio. To ensure scalability, it introduces a hierarchical algorithm, which is called zone-based routing. The...
