As in recent years, panelists included Ron Rivest and Adi Shamir - the R and S in the RSA cryptosystem. They were joined by Carmela Troncoso, an assistant professor at Switzerland's École Polytechnique Fédérale de Lausanne, whose work focuses on analyzing, building and deploying secure and privacy-preserving systems. Also on the panel: Ross Anderson, a professor of security engineering at both the University of Cambridge and the University of Edinburgh, founder of the discipline of security economics and author of the textbook "Security Engineering - A Guide to Building Dependable Distributed Systems." Moderating was Zulfikar Ramzan, chief digital officer at RSA - the security firm that runs the eponymous conference - who dived headfirst into one aspect of the "crypto" debate.
