Quantum safe CERTificate Infrastructure for Resilient Trust
Keeping Europe's digital trust secure in the quantum era
QCERT builds a quantum-resilient public key infrastructure (PKI) so that the certificates behind e-signatures, digital identity and secure web connections remain trustworthy once quantum computers can break today's cryptography.

What QCERT does
Four technical building blocks, tested in real pilots
WP2
Hybrid CA Toolkit
Dual-mode certificate issuance so authorities can sign with classical and post-quantum algorithms side by side.
WP3
Merkle Tree Certificates
Compact, verifiable certificate encodings that keep post-quantum signatures practical at scale.
WP4
PQC-aware TLS
Extending TLS 1.3 handshakes with post-quantum key exchange and signatures, end to end.
WP5
Interoperability & migration
Converters, adapters and validation APIs that bridge legacy PKI and quantum-safe trust.
