I recently had the pleasure of speaking at the Crypto & Privacy Village, which is part of the massive DEF CON computer security conference (and which I help organize). My talk was about a topic that basically everyone seems to be interested in: Can you invoke your Fifth Amendment right against self-incrimination when the police demand that you unlock your smartphone? The answer, unsurprisingly, is: It depends. I'm still waiting for video of the talk to go up on DEF CON's YouTube channel, and it'll be posted here on the CIS website once it does. But in the meantime, some folks have asked for my slides, so I'm attaching them here. (N.B. I should clarify something about the slide that mentions full-disk encryption: lately Android is moving from FDE to file-based encryption. This doesn't change the legal analysis.)
Thank you again to the Crypto & Privacy Village for having me, and thanks to the full house of attendees who turned out to see me speak!
