Quantum-Resistant Password Authenticated Connection Establishment

As part of a bigger research effort on the migration of electronic identity documents (eCards) to quantum-resilient schemes, we concentrate on the PACE protocol which is at the heart of many eCard security mechanisms. This includes the analysis of the current state-of-the-art in both PQC and eCards, the underlying infrastructures, challenges, and possible solutions starting from the hardware and infrastructures, over scheme suitability and protocol design, and all the way up to a full-scale approach for PQC migration and crypto-agility. The proposed research helps paving the way towards securing eCards against the threat of quantum computers, enable crypto-agility, and provide building blocks for similar systems.
