The paper “Whom You Gonna Trust? A Longitudinal Study on TLS Notary Services” by Georg Merzdovnik, Klaus Falb, Martin Schmiedecker, Artemios Voyiatzis and Edgar Weippl has been accepted for publication in the 30th Annual IFIP WG 11.3 Working Conference on Data and Applications Security and Privacy (DBSec 2016) which takes place from July, 18th-21th, 2016 in Trento, Italy. DBSec 2016 is an A-ranked conference in CORE.

Abstract: TLS is currently the most widely-used protocol on the Internet to facilitate secure communications, in particular secure web browsing. TLS relies on X.509 certificates as a major building block to establish a secure communication channel. Certificate Authorities (CAs) are trusted third parties that validate the TLS certificates and establish trust relationships between communication entities. To counter prevalent attack vectors – like hacked CAs issuing fraudulent certificates and active man-in-the-middle (MitM) attacks – TLS notary services were proposed as a solution to verify the legitimacy of certificates using alternative communication channels.
In this paper, we are the first to present a long-term study on the effectiveness of TLS notary services. We evaluated the services using active performance measurements over a timespan of one year, and discuss the effectiveness of TLS notary services in practice. Based on our findings we propose the usage of multiple notary services in conjunction with a semi-trusted centralized proxy approach, so as to protect arbitrarily-sized networks on the network level without the need to install any software on the client machines. Lastly, we identify multiple issues that prevent the widespread use of TLS notary services in practice, and propose steps to overcome them.

Katharina Krombholz @ “Lange Nacht der Forschung” kick-off event

Katharina Krombholz was invited to participate in the kick-off event and press conference of “Lange Nacht der Forschung” together with Gerald Klug (technology minister), Hannes Androsch (Austrian Council for Research and Technology Development) and Clara Eibensteiner (bmvit-research trainee).

Lange Nacht der Forschung

Martin Schmiedecker and Sebastian Neuer gave insights into how hackers really worked in contrast to the what is portrayed in movies. A second exhibit showed how mobile devices may compromise their owners’ privacy.
