Quantum LDPC codes (ComSec track April meeting)

Speaker: Olai Mostad (Simula UiB) Title: Quantum LDPC codes Abstract: Recently, there has been some debate on how many qubits a quantum computer needs to be cryptographically relevant. Last year, the best educated guess was one million, and today it is 10,000. We will take a look at one of the main reasons for the drastic cut […]

Superposition Attacks Against LPN-Based Authentication Protocols (monthly QComSec track meeting)

Speaker: Manuel Goulão Paper: https://eprint.iacr.org/2025/1506 Title: Superposition Attacks Against LPN-Based Authentication Protocols Abstract: Quantum security most commonly encompasses only offline passive quantum attacks, where a quantum computer is used by an adversary to solve some computationally hard problem, e.g. factoring or discrete logarithm. However, we are witnessing major efforts for the development and deployment of […]
