We present the first statistically private 3-server DPF for domain size $N$ with subpolynomial key size $N^{o(1)}$. We also present a similar perfectly private 4-server DPF. Our constructions offer benefits over their computationally secure counterparts, beyond the superior security guarantee, including better computational complexity and better protocols for distributed key generation, all while having comparable communication complexity for moderate-sized parameters.

In this work, we first systematically analyze the state of the art in defenses for both software exploitation and fault attacks on embedded systems. We then carefully design a holistic instruction set extension to augment the RISC-V instruction set architecture with instructions to deter against the threats analyzed in this work. Moreover we implement our design using the gem5 simulator system and a binary translation approach to arm software with our instruction set extension. Finally, we evaluate performance overhead on the MiBench2 benchmark suite. Our evaluation demonstrates a ROM overhead increase of 20% to defeat the aforementioned attacks.

Eindhoven University of Technology
The research will focus on
* quantum cryptography beyond QKD, e.g. key recycling, unclonable encryption, unclonable credentials, quantum PUFs and similar schemes.
* theory related to the Quantum Communication testbed under development in Eindhoven.
The research takes place in the EIPSI institute, which is a collaboration between the Security group and the Coding and Cryptology group.
This position is part of a large, long term, well-funded national program on quantum technologies (Quantum Delta NL). One of the three development lines (Catalyst-2, or CAT2) is fully dedicated to Quantum Key Distribution, Communication and Quantum internet.

In this work, we propose a (fully homomorphic) encryption scheme that supports a simple $t$-out-of-$n$ threshold decryption protocol while allowing for a polynomial modulus. The main idea is to use the Rényi divergence (as opposed to the statistical distance as in previous works) as a measure of distribution closeness. This comes with some technical obstacles, due to the difficulty of using the Rényi divergence in decisional security notions such as standard semantic security. We overcome this by constructing a threshold scheme with a weaker notion of one-way security and then showing how to transform any one-way threshold scheme into one guaranteeing semantic security.
