Secure Messaging for Normal People presented at Defcon 2015

by Justin Engler,

Summary : "Secure" messaging programs and protocols continue to proliferate, and crypto experts can debate their minutiae, but there is very little information available to help the rest of the world differentiate between the different programs and their features. This talk will discuss the types of attacks various secure messaging features can defend against so those who are tech-savvy but not crypto-experts can make informed decisions on which crypto applications to use.
This talk is intended for people with no preexisting cryptography knowledge. There will be no math or programming knowledge required. The goal is to explain secure messaging concepts such as PKI, PFS, and key validation without diving into heavier crypto, math, or programming content.
