A security proof for 802.11s protocols

Doug Kuhlman, Former student of Professor Nigel Boston now with Motorola research

Abstract:

The IEEE 802.11s working group was tasked to provide ways of establishing and securing a wireless mesh network. One proposal established a Mesh Security Architecture (MSA), with a developed key hierarchy and full protocol definitions. This talk examines the correctness and security of the MSA proposal and its corresponding protocols. Protocol Composition Logic (PCL) is utilized to prove individual protocols secure, as well as their composition. We add to the structure of PCL, generalizing it for peer-to-peer applications. We also discuss two security issues discovered with original versions of the proposals and proposed remedies.

Bio: Dr. Doug Kuhlman received his bachelor's degree in mathematics, computer science, and religion from Wartburg College in 1995.
