Last October I gave a talk titled “What Happened to the Crypto Dream?” where I looked at why crypto seems to have done little for personal privacy. The reaction from the audience (physical and online) was quite encouraging — not that everyone agreed, but they seemed to find it thought provoking — and several people asked me if I’d turn it into a paper. So when Prof. Alessandro Acquisti invited me to contribute an essay to the “On the Horizon” column in IEEE S&P magazine, I jumped at the chance, and suggested this topic.
While I’m not saying anything earth shaking, I do make a somewhat nuanced argument — I distinguish between “crypto for security” and “crypto for privacy,” and further subdivide the latter into a spectrum between what I call “Cypherpunk Crypto” and “Pragmatic Crypto.” I identify different practical impediments that apply to those two flavors (in the latter case, a complex of related factors), and lay out a few avenues for action that can help privacy-enhancing crypto move in a direction more relevant to practice.
I’m aware that this is a contentious topic, especially since some people feel that the time is ripe for a resurgence of the cypherpunk vision. I’m happy to hear your reactions.
