1 The H2020 PQCRYPTO project Andreas Hülsing 05 October rd ETSI/IQC Workshop on Quantum-Safe Cryptography
2 Post-Quantum Cryptography for Long-term Security Project funded by EU in Horizon Starting date 1 March 2015, runs for 3 years. 11 partners from academia and industry, TU/e is coordinator Andreas Hülsing PQCRYPTO project 2
3 Impact of PQCRYPTO All currently used public-key systems on the Internet are broken by quantum computers. Today s encrypted communication can be (and is being!) stored by attackers and can be decrypted later with quantum computer think of medical records, legal proceedings, and state secrets. Post-quantum secure cryptosystems exist but are under-researched we can recommend secure systems now, but they are big and slow Andreas Hülsing PQCRYPTO project 3

5 Impact of PQCRYPTO All currently used public-key systems on the Internet are broken by quantum computers. Today s encrypted communication can be (and is being!) stored by attackers and can be decrypted later with quantum computer think of medical records, legal proceedings, and state secrets. Post-quantum secure cryptosystems exist but are under-researched we can recommend secure systems now, but they are big and slow hence the logo. PQCRYPTO will design a portfolio of high-security post-quantum public-key systems, and will improve the speed of these systems, adapting to the different performance challenges of mobile devices, the cloud, and the Internet. PQCRYPTO will provide efficient implementations of high-security post-quantum cryptography for a broad spectrum of real-world applications. Andreas Hülsing PQCRYPTO project 3
6 Work packages Technical work packages WP1: Post-quantum cryptography for small devices Leader: Tim Güneysu, co-leader: Peter Schwabe WP2: Post-quantum cryptography for the Internet Leader: Daniel J. Bernstein, co-leader: Bart Preneel WP3: Post-quantum cryptography for the cloud Leader: Nicolas Sendrier, co-leader: Lars Knudsen Non-technical work packages WP4: Management and dissemination Leader: Tanja Lange WP5: Standardization Leader: Walter Fumy Andreas Hülsing PQCRYPTO project 4
7 WP1: Post-quantum cryptography for small devices Find post-quantum secure cryptosystems suitable for small devices in power and memory requirements (e.g. smart cards with 8-bit or 16-bit or 32-bit architectures, with different amounts of RAM, with or without coprocessors). Develop efficient implementations of these systems. Investigate and improve their security against implementation attacks. Deliverables include reference implementations and optimized implementations for software for platforms ranging from small 8-bit microcontrollers to more powerful 32-bit ARM processors. Deliverables also include FPGA and ASIC designs and physical security analysis. Andreas Hülsing PQCRYPTO project 5
8 WP2: Post-quantum cryptography for the Internet Find post-quantum secure cryptosystems suitable for busy Internet servers handling many clients simultaneously. Develop secure and efficient implementations. Integrate these systems into Internet protocols. Deliverables include software library for all common Internet platforms, including large server CPUs, smaller desktop and laptop CPUs, netbook CPUs (Atom, Bobcat, etc.), and smartphone CPUs (ARM). Aim is to get high-security post-quantum crypto ready for the Internet. Andreas Hülsing PQCRYPTO project 6
9 WP3: Post-quantum cryptography for the cloud Provide 50 years of protection for files that users store in the cloud, even if the cloud service providers are not trustworthy. Allow sharing and editing of cloud data under user-specified security policies. Support advanced cloud applications such as privacy-preserving keyword search. Work includes public-key and symmetric-key cryptography. Prioritize high security and speed over key size. Andreas Hülsing PQCRYPTO project 7
