“ digital custody solutions for consumers as well as institutional customers [17, 23, 30, 40, 45, 49–51] which have an estimated market size of nearly 500 billion USD [18].”

NIST competition for 'threshold cryptography' = resilient and resilient to Byzantine faults https://csrc.nist.gov/pubs/ir/8214/c/ipd

Our thesis project follows a 6-month long preliminary work with Pierre-Alain Fouque, who is co-inventor of the new lattice-based signature resilient to quantum computers, called 'Falcon' and winner of the NIST competition( https://www.inria.fr/fr/algorithme-falcon-cryptographie-postquantique-nist )

Intense international activity on quantum-resilient threshold signatures (search the keyword 'threshold signatures' in A*-rated security and cryptogtraphy conferences: Eurocrypt, Crypto, Asiacrypt, CCS, S&P)

---> We have clear ideas how to make it distributed and tolerant to Byzantine faults.
---> We have clear ideas how to anonymise the participating machines, using lattice-based zero-knowledge proofs

Compétences requises
