Dear colleagues,

I am happy to announce the second talk of the NetSec Lecture Series [1] that is organized by the GI Netsec working group [2]. On May 19th, 5pm (CEST), Jens Hiller from RWTH Aachen will tell a story of experimentation and centralization: Tracking the deployment of TLS 1.3 on the Web.

*Tracking the deployment of TLS 1.3 on the Web: A story of experimentation and centralization*

*Abstract:* Transport Layer Security is the most important security protocol on the Web. Before the standardization of its newest version TLS 1.3 in August 2018, the protocol was redesigned over four years in a yet unprecedented design process that involved many cryptographers and key industry stakeholders. Based on the combination of active Internet scans, and passive measurements in large networks and on Android devices, we will look at how large stakeholders experimented with the protocol in the Internet well before its standardization. Their experiments uncovered incompatibilities that influenced the ongoing standardization process. Also, we will analyze the uptake of this mission-critical security protocol after its standardization. In contrast to TLS 1.2, where adoption took more than five years and was prompted by severe attacks on previous versions, TLS 1.3 is deployed surprisingly speedily. The design process thus provides valuable information for future protocol design and deployment.

*CV:* Jens Hiller is Researcher and PhD Student at the Chair of Communication and Distributed Systems (COMSYS) at RWTH Aachen University. His research interests revolve around today's prominent secure communication protocols and security and privacy for the Internet of Things. He also spent two summer research stays at the International Computer Science Institute (ICSI) in Berkely analyzing the security of the Web's Internet Public Key Infrastructure.
