Secure Multi-party Computation (MPC) allows a set of mutually distrusting parties to jointly
evaluate a function on their private inputs while maintaining input privacy. In this work, we …

Designing an efficient cipher was always a delicate balance between linear and non-linear
operations. This goes back to the design of DES, and in fact all the way back to the seminal …

User-centric digital identity initiatives are emerging with a mission to shift control over online
identity disclosures to the individual. However, there is little representation of prospective …

Current architectures to validate, certify, and manage identity are based on centralised, top-
down approaches that rely on trusted authorities and third-party operators. We approach the …

Bitcoin is a decentralized cryptocurrency that uses a ledger (or “blockchain”) to keep track of
the transactions made between its users. Because it is a fully decentralized system and …

A processor-implemented method improves security in a blockchain network of devices,
which supports a blockchain, by protecting security, privacy, financial fairness, and secure …

Secure Multi-party Computation (MPC) allows to securely compute on private data. To make
MPC practical, logic synthesis can be used to automatically translate a description of the …

(57) ABSTRACT A processor-implemented method facilitates identity exchange in a
decentralized setting. A first system performs a pseudonymous handshake with a second …

User's digital identity information has privacy and security requirements. Privacy
requirements include confidentiality of the identity information itself, anonymity of those who …

This chapter discusses how the theories that underpin much research in crime science can
contribute to thinking about the future and how they were used to identify emerging …
