Today's study group was on the now a little dated paper of 2009 'Crying Wolf: An Empirical Study of SSL Warning Effectiveness' [1], which was published at USENIX. In cryptography research, it is easy to overlook implementation and usability and instead focus on theory. As is succinctly explained in Randall Munroe's well-known comic , the weaknesses in our cryptographic solutions are seldom in the constructions themselves, but in their real-world application. This paper explores the use and desig
