Finalists in NIST Lightweight Crypto Competition

The US National Institute of Science and Technology (NIST) has announced the 10 finalists for the last round of the Lightweight Crypto (LWC) Competition.
The goal of this competition is to standardize a lightweight authenticated encryption algorithm suitable for constrained environments.
It started in 2019 with 56 Round-1 candidates and is expected to select a winner for standardization in 2022.

We are very proud that the finalists include all our 3 submissions:

  • Ascon, previously selected as primary choice for lightweight cryptography by the CAESAR committee, designed by Christoph Dobraunig, Maria Eichlseder, Florian Mendel, and Martin Schläffer

  • ISAP, a design with inherent robustness against certain implementation attacks, designed by Christoph Dobraunig, Maria Eichlseder, Stefan Mangard, Florian Mendel, Bart Mennink, Robert Primas, and Thomas Unterluggauer

  • Elephant, a parallel design by Tim Beyne, Yu Long Chen, Christoph Dobraunig, and Bart Mennink.

For the full list of 10 finalists, see NIST.

Best Paper Award at CANS 2020

We are happy to announce that the paper “An Attack on Some Signature Schemes Constructed from Five-Pass Identification Schemes” by Daniel Kales and Greg Zaverucha has won a Best Paper Award at the 19th International Conference on Cryptology and Network Security (CANS 2020). Check out the paper (eprint) and the presentation on YouTube.

IAIK Christmas Special 2020

The “IAIK Christmas Special” is a yearly unique show that reviews what happened in InfoSec in 2020 and showcases recent hacks and exploits. With 300-500 viewers in a packed lecture hall, it cannot take place offline this year – now it takes place online and we will make it a better and greater show than any year before.

We invited 5 InfoSec guests, a music live act, and of course, most importantly: exciting hacks, exploits, and demos.

This special lecture is part of the TU Graz SSD and InfoSec courses.

Jakob Heher is awarded WKO research stipend

Jakob Heher is currently working on his master’s thesis on the security of online learning platforms, for which he has now received the WKO Forschungsstipendium 2020/21! The stipend will be awarded in an award ceremony in 2021. The WKO Steiermark annually awards 20 students, who are honoured with a grant of €2100 for the development of master’s theses with high economic relevance. Congratulations!

In his thesis, Jakob is investigating the security of several online learning platforms recommended for schools. These platforms are currently experiencing a sharp increase in users due to the COVID-19 pandemic. He has already reported several critical issues to software vendors in responsible disclosure processes.

Further details on the grant are provided by WKO.

Sujoy Sinha Roy joins IAIK as Assistant Professor

We welcome Sujoy Sinha Roy as assistant professor in cryptographic engineering at IAIK. Sujoy is interested in the implementation aspects of cryptography. He is a co-designer of ‘Saber’ which is a finalist in NIST’s Post-Quantum Cryptography Standardization Project. He received the PhD degree in 2017 with ‘Summa cum laude with congratulations from the examination committee’ from COSIC, KU Leuven, Belgium. His doctoral thesis was awarded the ‘IBM Innovation Award 2018’ that recognizes an outstanding doctoral thesis in informatics. Before joining TU Graz, he worked as an assistant professor at the University of Birmingham’s Security and Privacy group.

SGS and TU Graz open Lamarr Security Research

SGS and TU Graz announce the opening of Lamarr Security Research, a non-profit research center focusing on information security and establishing trust in digital systems and products. This new research environment is open for partner sponsors to work together, and to make the world a safer place.

Peter Grassberger awarded funding by Digitale TU Graz

IAIK student Peter Grassberger has been awarded a funding of 6.000€ for a project extending his Master’s Thesis. The funding is provided by Digitale TU Graz and Vice Rector for Digitalisation and Change Management Claudia von der Linden.
In his project, Mr. Grassberger develops a system which enables students to receive their graduation diploma (e.g. Bachelor’s Degree) or course transcript in digital form. The student can then share their diplomas electronically with universities or future employers.

IAIK, and especially the advisers Andreas Abraham and Stefan More, congratulate on this achievement!
