From a research point of view, we have provided to the community a full list of 118 papers, published in the best international conferences in cryptography. Our publications cover the three initial objectives of PROMETHEUS since they are related to
- foundations, with computational problems, cryptanalysis and basic tools;
- basic primitives, with digital signatures, encryption mechanisms and some building blocks for practical advanced protocols;
- privacy-preserving advanced cryptographic protocols.
On standardisation aspect, we have been strongly involved in the NIST standardisation competition, as we have initially been implied in many candidates. All along the project, we have evaluated and defended NIST competitors. Over the four algorithms selected by the NIST, three of them have been developed by at least one partner of the PROMETHEUS project. We have also been involved in the ISO/IEC and the ETSI process for their preparation in the future post-quantum standards.
From an implementation view, we have provided to the community and the industry a set of practical tools to help them in the transition to quantum-resistant cryptography:
- on foundations, we have design open-source software for estimating the security of lattice-based cryptography: LWE-Estimator, LWE-Leaky-Estimator, and NTRU Fatigue;
- on basic primitives, with the publication of several implementations of the NIST competitors, taking into account side-channel attacks and the implementation of some advanced cryptographic primitives such as blind signatures, or proofs of knowledge.
Eventually, the last period of the project has strongly been dedicated to the illustration of all our work with the finalisation of our four use cases:
- the first quantum-resistant e-payment system;
- the first quantum resistant e-voting system;
- a quantum-resistant identity wallet to protect the privacy of individuals in proximity services;
- a cyber threat intelligence system protecting sensitive data.
For each of them, we have provided the design, the implementation and the validation in the respective deliverables within WP6.
We have also worked on the ethical aspects of our project. Following an EC request, we have created an External Ethical Committee (EEC) with which we have interacted several times during the lifetime of the project to refine our research work, and the way to use it in our use cases. We have also worked on gender and equal opportunity (GEO) with several innovative initiatives concerning (i) an internal code of conduct and (ii) the design of an internal survey about gender and equal opportunity activities within each institution inside our consortium.
All along the project, our dissemination activity has been done through our website, which is available at this address:
https://www.h2020prometheus.eu(odnośnik otworzy się w nowym oknie) It publicly provides all the 118 project publications and the way to download them. It also gives some news of the results we have obtained (regarding publications and standardisation activities) or the events in which we have participated. Besides, PROMETHEUS members have also communicated about those main activities using our dedicated Twitter account
https://twitter.com/h2020prometheus(odnośnik otworzy się w nowym oknie). Our dissemination and communication activities have also been done thanks to several private meetings with some important stakeholders such as security (ANSSI) and privacy (CNIL) agencies and our PROMETHEUS industrial workshop that we have organised at Orange Gardens in Chatillon, near Paris, in June 28, 2022.
Regarding exploitation, we have provided our final business plan and exploitation report, which describes
- our short-term exploitation of lattice-based signatures and encryption, stating that the transition to post quantum cryptography should be thought today as efficiency is there, and compatible with current real-life needs;
- a proposal for a middle to long-term exploitation of advanced use cases.
