POSEIDON
Post-Quantum Secure Digital Identities for European Solutions
Securing Europe’s digital future
As quantum computing progresses, traditional cryptography faces increased risks. This threatens the safety of online communications, sensitive data, and digital identities throughout Europe. In this context, the EU-funded POSEIDON project aims to create practical and scalable post-quantum cryptography (PQC) solutions. By testing these tools in real-world, high-impact situations, POSEIDON will improve digital identity management, protect data during transit and storage, and offer advice for adopting quantum-safe protocols in both public and private systems. The project’s innovations will support cybersecurity standards and policies across the EU, keeping citizens and businesses secure amid rapidly changing digital threats.
