Fingerprints are so 90s


A few years back I prepared a presentation on the so-called Socialist Millionaires' Protocol (SMP) for a university seminar. SMP is a solution to the problem of key authentication devised for OTR (Off-the-Record), the system for instant-messaging encryption.

Today I held a short version of the presentation for non-mathematicians at the CCC Hamburg. For the benefit of the Internet, the awesomely hand-made slides are in English. There is also a handy hand-out with a protocol diagram.

The written presentation for the course is completely in German and math-rich. I did try hard to make it a clear read for the so-inclined. Have fun! :)
