One unfortunate fact about protocols is that as they get older and applied to more scenarios — and TLS is used basically everywhere — they tend to gain weight....Eric Rescorla From Communications of the ACM | February 2017
We systematically test popular TLS implementations and find unexpected transitions in many of their state machines that have stayed hidden for years. We show how...Benjamin Beurdouche, Karthikeyan Bhargavan, Antoine Delignat-Lavaud, Cédric Fournet, Markulf Kohlweiss, Alfredo Pironti, Pierre-Yves Strub, Jean Karim Zinzindohoue From Communications of the ACM | February 2017
