Security issues of CFS-like digital signature algorithms
Giuseppe D'Alconzo, Alessio Meneghetti, Paolo Piasenti
We analyse the security of some variants of the CFS code-based digital signature scheme. We show how the adoption of some code-based hash-functions to improve the efficiency of CFS…
A survey on NIST PQ signatures
Nicola Di Chiano, Riccardo Longo, Alessio Meneghetti +1
Shor's shockingly fast quantum algorithm for solving the period-finding problem is a threat for the most common public-key primitives, as it can be efficiently applied to solve bot…
A Provably-Unforgeable Threshold EdDSA with an Offline Recovery Party
Michele Battagliola, Riccardo Longo, Alessio Meneghetti +1
A -threshold signature scheme enables distributed signing among players such that any subset of size at least can sign, whereas any subset with fewer players cannot.…
Threshold ECDSA with an Offline Recovery Party
Michele Battagliola, Riccardo Longo, Alessio Meneghetti +1
A threshold signature scheme enables distributed signing among players such that any subgroup of size can sign, whereas any group with fewer players cannot. Our go…
A new ECDLP-based PoW model
Alessio Meneghetti, Massimiliano Sala, Daniele Taufer
We lay the foundations for a blockchain scheme, whose consensus is reached via a proof of work algorithm based on the solution of consecutive discrete logarithm problems over the p…
A survey on efficient parallelization of blockchain-based smart contracts
Alessio Meneghetti, Tommaso Parise, Massimiliano Sala +1
The main problem faced by smart contract platforms is the amount of time and computational power required to reach consensus. In a classical blockchain model, each operation is in…
Two-tier blockchain timestamped notarization with incremental security
Alessio Meneghetti, Armanda Ottaviano Quintavalle, Massimiliano Sala +1
Digital notarization is one of the most promising services offered by modern blockchain-based solutions. We present a digital notary design with incremental security and cost reduc…
