Title: Securing Cryptographic Systems against Quantum Adversaries and
Hardware Exploits

Date: 20 November 2018, Tuesday

Time: 16:00

Place: SCI 103

Host: Alptekin Küpçü


Cryptography is essential for building trust into electronic world.

Securing cryptographic systems of the future requires using new
theoretical and physical defenses. On the one hand, developments in
quantum computing technologies are threatening hard mathematical
problems that existing cryptographic systems rely on. On the other
hand, deployment of embedded systems into the Internet-of-Things
enables physical access to hardware, opening a new attack surface for
exploits. In this talk, I will present a series of systems that can
mitigate such powerful attacks. In the first part of the talk, I will
analyze implementations of future cryptographic systems that can
withstand theoretical quantum cryptanalysis. I will first demonstrate
new techniques to break into these post-quantum encryption systems
purely by observing the power consumption of the hardware and then
propose low-overhead defenses to mitigate such vulnerabilities. In the
second part of the talk, I will describe systems to secure the
hardware root of trust against physical readout and side-channel
attacks. I will describe methods for engraving unique digital keys
deep into the hardware through physical unclonable functions – a
hardware security primitive to construct digital fingerprints from
process manufacturing variations – and demonstrate a novel method for
secure key generation in hardware.
