Blockchains offer a decentralized, immutable and verifiable ledger that can record
transactions of digital assets, provoking a radical change in several innovative scenarios …

Self‐sovereign identity is the next evolution of identity management models. This survey
takes a journey through the origin of identity, defining digital identity and progressive …

Cryptography, in particular public-key cryptography, has emerged in the last 20 years as an
important discipline that is not only the subject of an enormous amount of research, but …

We argue that the random oracle model—where all parties have access to a public random
oracle—provides a bridge between cryptographic theory and cryptographic practice. In the …

Cryptography is concerned with the conceptualization, definition, and construction of
computing systems that address security concerns. The design of cryptographic systems …

Deep Neural Networks have recently gained lots of success after enabling several
breakthroughs in notoriously challenging problems. Training these networks is …

This beginning graduate textbook describes both recent achievements and classical results
of computational complexity theory. Requiring essentially no background apart from …

It is shown how to distribute a secret to n persons such that each person can verify that he
has received correct information about the secret without talking with other persons. Any k of …

Important decisions about people are increasingly made by algorithms: Votes are counted;
voter rolls are purged; financial aid decisions are made; taxpayers are chosen for audits; air …

We propose a novel paradigm for defining security of cryptographic protocols, called
universally composable security. The salient property of universally composable definitions …
