RFC 5408 which describes a Security Architecture for Identity-Based Encryption. It includes protocols for key requests and public parameter requests as well as some basic building blocks for federation. The system described is similar to what Voltage uses for their IBE based encryption solutions. If you are interested in how Identity-Based Encrpytion systems scale in practice and don’t mind reading RFCs, it is a worthwhile read.

Thanks to my co-authors Mark Schertler and Luther Martin. Specifically Luther deserves the majority of the credit for moving this through the process over the past two (or more?) years. Also thanks to Terence Spies at Voltage, as well as Eric Rescorla, Tim Polk and Blake Ramsdell at the IETF for their support.

The World Economic Forum named myself and Voltage a Technology Pioneer for 2006/2007 (they name both a specific individual and a company). I feel incredibly humbled. The story is covered in Time Magazine.

I finally submitted my thesis and received my Ph.D. My thesis is on the publications page. The main lesson learned : Only fools try to do a start-up and write a thesis at the same time. And it seems the smartest students drop out of the program to and start Yahoo! or Google anyways.
