Tuomas Aura received his doctoral degree from Helsinki University of Technology, Finland, in 2000. His thesis was on authorization and availability in open networks. Since then, he has been working on network and software security at Microsoft Research in Cambridge, UK. The current focus is the security and privacy in mobility protocols.

Title of the IWWST 2005 keynote address
Challenges in Wireless LAN security

Abstract
Wireless LAN security has received a lot of attention, mainly because of the cryptographic flaws found in the WEP protocol. The cryptography is, however, relatively easy to fix by replacing the algorithms. There are other, architectural, issues that seriously limit the usefulness of the wireless LAN security mechanisms. These problems have received much less attention even though they are much harder to solve. In this talk I will discuss some of the architectural challenges in securing wireless networks.
