DeepSec 2016 Talk: Systematic Fuzzing and Testing of TLS Libraries – Juraj Somorovsky

Published on November 8, 2016 By sanna

In his talk Juraj Somorovsky presents TLS-Attacker, a novel framework for evaluating the security of TLS libraries. Using a simple interface, TLS-Attacker allows security engineers to create custom TLS message flows and arbitrarily modify TLS message contents in order to test the behavior of their TLS libraries. Based on TLS-Attacker, he and his team first developed a two-stage TLS fuzzing approach. […]

DeepSec 2016 Talk: TLS 1.3 – Lessons Learned from Implementing and Deploying the Latest Protocol – Nick Sullivan

Published on October 19, 2016 By sanna

Version 1.3 is the latest Transport Layer Security (TLS) protocol, which allows client/server applications to communicate over the Internet in a way that is designed to prevent eavesdropping, tampering, and message forgery. TLS is the S in HTTPS. TLS was last changed in 2008, and a lot of progress has been made since then. CloudFlare […]

DeepSec 2016 Workshop: Deploying Secure Applications with TLS – Juraj Somorovsky

Published on September 9, 2016 By sanna

Cryptography is all around us. It has become something like the background radiation of the networked world. We use it on a daily basis. Since nothing usually comes into existence by mistake, there must be someone responsible for deploying this crypto stuff. You are right. Software developers, mathematicians, engineers, system administrators, and many more people […]

Deep Sec2016 Talk: DROWN – Breaking TLS using SSLv2 – Nimrod Aviram

Published on September 5, 2016 By sanna

In the past years encrypted communication has been subject to intense scrutiny by researchers. With the advent of Transport Layer Security (TLS) Internet communication via HTTP became a lot more secure. Its predecessor Secure Sockets Layer (SSL) must not be used any more. The real world has its own ideas. SSLv2 and SSLv3 is still […]

DeepSec Video: illusoryTLS – Nobody But Us. Impersonate,Tamper and Exploit

Published on February 15, 2016 By lynx

Cryptographic backdoors are a timely topic often debated as a government matter to legislate on. At the same time, they define a space that some entities might have practically explored for intelligence purposes, regardless of the policy framework. The Web Public Key Infrastructure (PKI) we daily rely on provides an appealing target for attack. The […]
