Northeastern University Wireless Security Laboratory (WSL)

Welcome to the Wireless Security Laboratory (WSL) of the College of Computer Science at Northeastern University. We are a cryptography group in the college and our research projects are focusing on various aspects of wireless network and computer security. In the past we have developed efficient software based stream ciphers (SSC2), and implemented various cryptographic libraries for Palm OS. We have also done research on the authenticated key exchange protocols, especially concerning low power constraints of some wireless devices. Further research effort has been put to investigating efficient algorithm for key distribution for dynamic group, and wireless network simulation.

	Centers of Academic Excellence in Information Assurance Education
	In May 2002, Northeastern University was designated as Centers of Academic Excellence in Information Assurance (IA) Education. This program is an outreach effort designed and operated by the National Security Agency (NSA) in the spirit of Presidential Decision Directive 63 (PDD 63), the Clinton Administration's Policy on Critical Infrastructure Protection, May 1998. The program goal is to reduce vulnerability in our National Information Infrastructure by promoting higher education in information assurance, and producing a growing number of professionals with IA expertise in various disciplines.

Projects

	Lightweight Cryptography
	Subcontract from Northwestern University, supported by DARPA(2000-2003) Under construction
	Authentication and Key Revocation Protocols for Wireless Networks
	Supported by DARPA(2000-2003) To maintain high quality of confidentiality and authenticity while still providing versatile key management solution and scalability capability for low-power devices in wireless networks, we investigate the following three areas, with special remark on the low power constraints of these wireless devices: Software-based Stream Cipher : to achieve fast data encryption rate on low-power devices. Mutually Authenticated Key Exchange Protocols : to provide efficient methods for parties with unequal computing power to authenticate and establish session keys over unreliable wireless network. Optimal Group-key Distribution Protocols : to allow effective key revocation of compromised and/or defected group members over an insecure broadcast channel.
