18-637 / 96-836 Wireless Network Security
With communication and network services and applications increasingly leveraging wireless media, the importance of information and network security in the wireless domain continues to grow. The challenges of providing secure communication and network services are considerably more difficult in wireless environments than in traditional wired systems (e.g., the Internet), so the focus of the course will be purely wireless environments such as wireless ad hoc, mesh, and sensor networks. Coverage will focus on wireless vulnerabilities and attacks at various layers of the protocol stack, spanning the stack from aspects of physical communication to application and service security issues. Focus will be placed on securing the operation and performance of wireless networks, with less emphasis on information security. Topics include MAC-layer misbehavior; selective packet dropping, modification, and insertion; jamming; distributed trust in ad hoc environments; reputation systems; and cross-layer attacks. Class material will be largely based on recent and current research; students will read and present recent research papers and participate in a group research project.
