Invited Speakers
Peter Schwabe
Tenured Faculty Member at Max Planck Institute for Security and Privacy, Germany; and Professor at Radboud University, the Netherlands
Introduction to Lattice-Based Key Encapsulation Mechanism (KEM) and Hash-Based Digital Signature Schemes
Short Biography
Peter Schwabe is research group leader at MPI-SP and professor at Radboud University. He graduated from RWTH Aachen University in computer science in 2006 and received a Ph.D. from the Faculty of Mathematics and Computer Science of Eindhoven University of Technology in 2011. He then worked as a postdoctoral researcher at the Institute for Information Science and the Research Center for Information Technology Innovation of Academia Sinica, Taiwan and at National Taiwan University. His research area is cryptographic engineering; in particular the security and performance of cryptographic software. He published more than 50 articles in journals and at international conferences presenting, for example, fast software for a variety of cryptographic primitives including AES, hash functions, elliptic-curve cryptography, and cryptographic pairings. He has also published articles on fast cryptanalysis, in particular attacks on the discrete-logarithm problem. In recent years he has focused in particular on post-quantum cryptography. He co-authored the "NewHope" and "NTRU-HRSS" lattice-based key-encapsulation schemes which were used in post-quantum TLS experiments by Google and is co-submitter of seven proposals to the NIST post-quantum crypto project, all of which made it to the second round and five of which made it to the third round.

The Security of Internet Protocols and Moving Towards Post-Quantum Transport Layer Security (TLS)
Short Biography
Dr. Douglas Stebila is an Associate Professor of cryptography in the Department of Combinatorics & Optimization at the University of Waterloo in Waterloo, Ontario, Canada. His research focuses on improving the security of key exchange protocols and Internet cryptography protocols such as TLS and SSH, including the development of quantum-resistant solutions. He is the leader of the Open Quantum Safe project, an open-source software project for prototyping and evaluating quantum-resistant cryptography. He holds an MSc from the University of Oxford and a PhD from the University of Waterloo, and held previous academic appointments at the Queensland University of Technology in Brisbane, Australia, and McMaster University in Hamilton, Ontario, Canada.

7.50 am - 8.00 am Opening Remarks
8.00 am - 9.00 am Douglas Stebila
The Security of Internet Protocols and Moving Towards Post-Quantum Transport Layer Security (TLS) - Part 1
Abstract: I’ll give a review of common Internet cryptography protocols like the Transport Layer Security (TLS) protocol, the Secure Shell (SSH) protocol, and the Signal secure messaging protocol. I’ll discuss the methods by which we formalize and analyze the security of these protocols.
9.00 am - 9.10 am Break
9.10 am - 10.10 am Douglas Stebila
The Security of Internet Protocols and Moving Towards Post-Quantum Transport Layer Security (TLS) - Part 2
Abstract: I’ll discuss the transition to post-quantum cryptography in the context of the TLS protocol. I’ll explain the "hybrid" or "composite" options, in which two algorithms – a traditional algorithm and a post-quantum one – are used simultaneously, and give an update on the progress towards standardization of these options. I’ll also present the KEMTLS alternative protocol design which uses long-term KEM keys for TLS handshake authentication instead of digital signatures, which can be more efficient for both communication and computation.
10.10 am - 10.25 am Question-and-Answer Session
10.30 am - 11.30 am Mustafa Khairallah
Authenticated Encryption and Tweakable Block Ciphers (TBCs)
Abstract: An authenticated encryption with associated data (AEAD) scheme is a symmetric-key scheme that performs both encryption and authentication simultaneously. It has become an essential part of the symmetric-key cryptography toolbox, with two recent major cryptographic competitions to design new AE schemes. The research on AE has led to the acceleration of research on tweakable block ciphers (TBC), a variant of classical block cipher that includes more parameterisation and leads to more efficient and more secure algorithms. In this talk, I will present the basic concepts, security notions and examples of authenticated encryption as well as tweakable block ciphers. I will also discuss the relation between the two primitives and how the tweakable block ciphers impacted the design of authenticated encryption schemes.
11.30 am - 11.40 am Break
11.40 am - 12.40 pm Mustafa Khairallah
Romulus: A Symmetric-Key Family of Algorithms from TBCs
Abstract: Romulus is a finalist in the NIST lightweight cryptography standardization project. It is designed by a team of cryptographers from major Asian institutions in Singapore, Japan and China. It includes three AEAD schemes with different security and performance goals, and an efficient hash function. In this talk, I will explain the different schemes, their security and performance. I will also touch on the design process of these schemes and will talk about their current implementations and possible future directions.
12.40 pm - 12.55 pm Question-and-Answer Session
12.55 pm - 2.30 pm Lunch break
2.30 pm - 3.30 pm Peter Schwabe
Introduction to Lattice-Based Key Encapsulation Mechanism (KEM)
Abstract: In the first part I will give an introduction to the design of lattice-based KEMs from a crypto-engineering perspective and explain why this category of post-quantum cryptography was represented with more proposals in the NIST PQC standardization project than any other category.
3.30 pm - 3.40 pm Break
3.40 pm - 4.40 pm Peter Schwabe
Introduction to Hash-Based Signatures
Abstract: In the second part of my talk, I will introduce hash-based signatures, arguably the most conservative asymmetric post-quantum construction. We will start with very simple one-time signatures, through stateful many-time signatures, and eventually arrive at the state of the art in stateless hash-based signatures: the SPHINCS+ signature framework.
4.40 pm - 4.55 pm Question-and-Answer Session
