Secure Update Propagation via Set-Homomorphic Signatures

In this document, we propose to use homomorphic signatures to maintain a consistent database across all nodes of distributed network.

Quantum Computing Threat: NIST PQC standards are here… how can you keep ahead?

Cryptographic agility and a clear roadmap to the NIST standards are key to a smooth and secure transition to PQC.

Quantum Computing Threat: An Overview of Post-Quantum Cryptography

The goal of this document is to provide the reader with an understanding of the key technical ideas used in post‐quantum cryptography.

Quantum Computing Threat: The First NIST Post-Quantum Cryptographic Standards

In 2016, the National Institute of Standards and Technology (NIST) launched a open and world‐ wide effort to propose, analyze and eventually standardize post‐quantum cryptographic schemes. In this white paper we find out more.

Secure Messaging in a Post-Quantum World

Team PQShield experts outline how PQC can be applied to secure messaging in a two-party setting, typically between mobile devices, as well as the specific performance and data requirements.

Cryptography Modernization Part 1: Where is your Cryptography?

A plain english guide to help you get ready to comply with the new cryptography standards.

Anonymous Reputation Systems Achieving Full Dynamicity from Lattices

In this work, we revisit the Anonymous Reputation Systems presented by Blömer et al. in (FC’15).

Attribute-Based Signatures for Unbounded Circuits in the ROM and Efficient Instantiations from Lattices

In this work, we affirmatively close the gap between ABS schemes based on bilinear maps and lattices by constructing the first lattice-based ABS scheme for unbounded circuits in the random oracle model.

Shorter Messages and Faster Post-Quantum Encryption with Round5 on Cortex M

Round5 is a Public Key Encryption and Key Encapsulation Mechanism (KEM) based on General Learning with Rounding (GLWR), a lattice problem. We implement Round5 on Cortex M4.

More efficient, provably-secure direct anonymous attestation from lattices

The Cloud-Edges (CE) framework, wherein small groups of Internet of Things (IoT) devices are serviced by local edge devices, enables a more scalable solution to IoT networks.

Unifying Leakage Models on a Rényi Day

In this work, we provide new strategies to prove the security of masked implementations.

More Efficient Algorithms for the NTRU Key Generation Using the Field Norm

This work shows how to speed up key generation for NTRU-based algorithms by 100x.
