    SUMMARY Researcher in Cryptography, Information Security, Blockchain, Multi-Party Computation, Zero-Knowledge Proofs, and Homomorphic Encryption. Experience of 8 years in cryptography and 4 years in decentralized technologies. ● Implemented in Rust an MPC ECDSA protocol from the paper UC Non-Interactive, Proactive, Threshold ECDSA with Identifiable Aborts [Canetti et al] and integrated it into the HexSafe wallet. ● Implemented the key-derivation process for MPC ECDSA to make it compatible with Ethereum wallets. ● Included non-interactive ZKP protocols in key-generation and pre-signing phases, such as Pedersen parameters, Paillier-Blum, and Schnorr. ● Successfully combined BFV Fully Homomorphic Encryption, Shamir Secret Sharing, and Zero-Knowledge Range Proofs to generate a privacy-preserving authentication scheme based on biometric templates in a decentralized network of ~100 nodes. ● Implemented the feature extraction of biometric templates using a Neural Network in Python with a Rust wrapper. A 50-layer ResNet was adapted to preserve the user's privacy. ● Developed an algorithm for generating the parameters of a new decentralized version of the BFV encryption scheme for 128 bits of security and prime numbers with lengths according to homomorphic encryption standards. ● As a result, we published a paper: ia.cr/2022/1673

    Sono ideatore di Business Comportamentale un sistema di analisi delle soft skill dei collaboratori e dei dipendenti aziendali. Business Comportamentale permette di tracciare la mappa del comportamento, tuo e dei tuoi collaboratori, in funzione dei risultati che stai ottenendo nel business e nella vita. L'applicazione del sistema nelle aziende clienti, fa di me un manager a tempo in posizione di HR Business Partner. A differenza delle società di consulenza che utilizzano gli strumenti di valutazione del potenziale delle persone per acquisire informazioni chiave per lo sviluppo di onerosi servizi da proporre al cliente, il mio sistema, sviluppato in oltre 15 anni di esperienza nel mondo del business, viene utilizzato per accellerare la crescita personale ed aziendale. Tutto ciò significa: più persone consapevoli delle proprie potenzialità e più aziende composte da individui in grado di esprimere il potenziale in pieno, verso la crescita e la prosperità. Le aziende che si espandono producono benessere e ricchezza per le persone. Sono arrivato a sviluppare Business Comportamentale per le diverse esperienze che ho fatto come imprenditore, manager e consulente aziendale, tra l’altro oggi continuo ad occuparmi di: • Marketing digitale: sono un manager per l’innovazione certificato da Manageritalia ed incluso nell’elenco pubblicato sul sito del Ministero dello Sviluppo Economico a cui le imprese che intendono fare domanda per il "Voucher Innovation Manager", possono attingere per lo sviluppo dei loro progetti. Occupo la posizione di Digital Strategist in alcune aziende mie clienti. • Consulenza aziendale: strategie di investor relations, sviluppo commerciale, internazionalizzazione e di business in Oman. Amo nutrire la mia mente con tutto ciò che è innovativo. Ho praticato diversi sport, ma quello che rimane nel mio cuore è il calcio. Ho un mantra: le persone stanno assieme se hanno valori comuni. Senza un progetto tutto implode. Mi piace essere d'aiuto alle startup. In tutti i progetti che seguo il mio punto di arrivo è l'espansione aziendale, se un progetto mi appassiona ne divento partner, scrivimi mi piacerebbe entrare in contatto.
