Horizon Cybersecurity: Post-Quantum & High-Assurance Cryptography

Funds €2-3M projects building post-quantum cryptographic schemes for digital ID wallets, or formally verified high-assurance cryptographic software.

OpenEuropean CommissionEU

Across the EU, digital identity wallets are becoming real infrastructure — the EU Digital Identity Wallet framework under eIDAS2 — and none of it holds up unless the cryptography underneath is trustworthy today and still safe once large quantum computers arrive. This call funds that cryptography. It sits inside Horizon Europe’s Cluster 3 (Civil Security), but day-to-day it’s run by the European Cy

Designing, building, and proving next-generation cryptography for the EU’s digital identity wallets and eIDs. A proposal addresses one of two tracks: new post-quantum (quantum-resistant) cryptographic schemes and protocols — digital signatures, entity authentication, authenticated key establishment over insecure networks, and password-based (PAKE) key exchange, sized for real wallet use cases — or High-Assurance Cryptographic Software (HACS): a shared specification language for cryptographic security properties, plus tools that give machine-checked, provable guarantees that software implements and uses cryptography correctly.
