Welcome to ARIAS
S Laboratory for Advanced Research in Information Assurance and Security

The technology for computing and networking systems has and continues to advance at a dramatic pace. However, the technology for ensuring the security and availability of those systems has not kept pace. Traditionally, security has not been considered as an essential element in the design or development process and was often added as an afterthought. As a result, today's systems are often plagued with numerous vulnerabilities that may be exploited by malicious users.

High-profile attacks and system exploits by malicious users have become common recurring events that increasingly threaten the very fabric of today's digital society. According to a survey conducted by the FBI's Computer Intrusion Squad, in 2004, a cyber crime occurred every 20 seconds and accounted for billions of dollars in lost revenues for corporations based in the United States.

The Advanced Research in Information Assurance and Security (ARIAS) lab is a research group within the Department of Electrical and Computer Engineering at Virginia Tech. It was established in 2003, and its mission is to study and solve challenging security problems in networks and computer systems. Currently, members of ARIAS are conducting research in the following areas:

• Key management in wireless sensor networks
• Intrusion detection in high-bandwidth networks
• IP traceback and MAC-layer traceback
• Attack-resilient routing in wireless ad hoc networks
• Trustworthy spectrum sharing in cognitive radio networks
• Detection of MAC-layer misbehaviors in wireless ad hoc networks
• Privacy enhancing technologies
