          Security Associations for Personal Devices

Short-range wireless networking is enormously popular. Many handheld
devices now support WiFi and Bluetooth. More such technologies are on
their way. Increasingly, short-range networking is used by ordinary
consumers who are not technically savy. This makes the the process of
setting up communication and security contexts particularly challenging.
Users find the setup procedures difficult, and often end up with insecure
communication.

During the last year or so, several standardization bodies have started
developing improved setup procedures for short-range wireless networking.
The challenge is to strike a balance among security, usability, and cost
overhead. Meeting this challenge required developing some novel
authentication and key agreement protocols.

I will describe the problem and the different protocols in emerging
standards specifications, discuss some preliminary results of usability
tests, and point to some open issues.
