Cob: a consensus layer enabling sustainable sharding-based consensus protocols
Andrea Flamini, Riccardo Longo, Alessio Meneghetti
In this paper we explore a context of application of Cob, a recently introduced Byzantine Fault Tolerant consensus protocol. Cob proves to be a leaderless consensus protocol which…
Cob: a Leaderless Protocol for Parallel Byzantine Agreement in Incomplete Networks
Andrea Flamini, Riccardo Longo, Alessio Meneghetti
In this paper we extend the \emph{Multidimensional Byzantine Agreement (MBA) Protocol}, a {leaderless} Byzantine agreement for lists of arbitrary values, into a protocol suitable f…
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…
Multidimensional Byzantine Agreement in a Synchronous Setting
Andrea Flamini, Riccardo Longo, Alessio Meneghetti
In this paper we will present the Multidimensional Byzantine Agreement (MBA) Protocol, a leaderless Byzantine agreement protocol defined for complete and synchronous networks that…
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…
Public Ledger for Sensitive Data
Riccardo Longo, Massimiliano Sala
Satoshi Nakamoto's Blockchain allows to build publicly verifiable and almost immutable ledgers, but sometimes privacy has to be factored in. In this work an original protocol is pr…
Several Proofs of Security for a Tokenization Algorithm
Riccardo Longo, Massimiliano Sala, Riccardo Aragona
In this paper we propose a tokenization algorithm of Reversible Hybrid type, as defined in PCI DSS guidelines for designing a tokenization solution, based on a block cipher with a…
On the security of the Blockchain Bix Protocol and Certificates
Riccardo Longo, Federico Pintore, Giancarlo Rinaldo +1
The BIX protocol is a blockchain-based protocol that allows distribution of certificates linking a subject with his public key, hence providing a service similar to that of a PKI b…
Key-Policy Multi-Authority Attribute-Based Encryption
Riccardo Longo, Chiara Marcolla, Massimiliano Sala
Bilinear groups are often used to create Attribute-Based Encryption (ABE) algorithms. In particular, they have been used to create an ABE system with multi authorities, but limited…
