PROMETHEUS aims to provide post-quantum signature schemes, encryption
schemes and privacy-preserving protocols relying on lattice. This requires to
- Cryptographic foundations.
Provide solid foundations for the design of
privacy-preserving cryptographic protocols resisting quantum adversaries. These
clarifying the exact hardness of algorithmic lattice problems in the
classical and quantum settings;
determining the relationships between the diverse lattice problems.
- Basic tools related to lattices.
Enable the secure and practical applicability of lattice trapdoors, which
typically consist of a short basis of some lattice and have been central
tools in the design of many lattice- based cryptographic protocols.
- Signature and encryption schemes.
Design and implement better lattice-based
signatures, encryption, commitment schemes and zero-knowledge proof systems
that can easily be combined altogether in higher- level protocols, and prove
their security even against side-channel attacks.
- Privacy-preserving protocols.
Provide concrete realisations of advanced
privacy-preserving protocols. These include the construction and
anonymous credentials and related mechanisms (group signatures, anonymous
truly anonymous e-cash systems and their
- electronic voting and other tools for e-democracy;
cryptographic tools related to cyber threat intelligence.
