Official call identifier: HORIZON-CL3-2027-02-CS-ECCC-03
Objective of the call
The objective of this call is to strengthen the security and trustworthiness of post-quantum cryptographic systems. It focuses on developing robust implementations of PQC schemes, advancing cryptanalysis and quantum hardness understanding, and enabling secure digital trust solutions for the post-quantum era.
Scope of activities
Projects should address one of the defined technology areas. This includes securing PQC implementations against side-channel, fault, and combined attacks, while balancing security and performance. Activities may cover development of automated testing frameworks and formal verification methods. Another area focuses on analysing quantum hardness, including the impact of new quantum algorithms and AI-supported attacks, and designing improved post-quantum schemes. A third area involves the development of quantum-resistant protocols supporting privacy-friendly applications, including electronic identities, verification systems, and digital trust solutions.
Eligible applicants
- Innovative SMEs, startups and enterprises aiming to scale and strengthen competitiveness
- Public-sector organisations driving transformation and societal impact
- Research and academic institutions commercialising knowledge
- Non-profit organisations delivering purpose-driven innovation
- Organisations based in EU Member States or Associated Countries (described in General Annex A, General Annex B, General Annex C)
- Minimum 3 independent partners from 3 eligible countries
Specific consortium we are looking for:
Consortia should include cryptography experts, cybersecurity researchers, and organisations specialising in post-quantum cryptography and cryptanalysis. Participation of research institutions working on quantum algorithms, AI-assisted security analysis, and formal verification is expected. Industry partners developing secure digital identity solutions, privacy-enhancing technologies, and real-world applications of PQC-based systems are also relevant.
