Distributing Trust with Blockchains
Cryptocurrencies on blockchains are worth billions today. Blockchain is promised to secure exchanges among unknown, mistrusting parties. Companies are struggling to explore new opportunities with the crypto-technology. What stands behind this hype? A blockchain is simply a public ledger for recording transactions, maintained by many nodes without central authority through a distributed cryptographic protocol. All nodes validate the information to be appended to the blockchain, and a cryptographic consensus protocol ensures that the nodes agree on a unique order in which entries are appended.
This talk will explore the cryptography and consensus mechanisms for blockchains. Public blockchains and cryptocurrencies like Bitcoin or Ethereum operate in a completely decentralized way. Consortium blockchains, on the other hand, are run by an a-priori established group.
The presentation will also cover Hyperledger Fabric, a modular and extensible blockchain platform that is developed open-source under the Hyperledger Project, with key contributions from IBM Research - Zurich.

Regulation and Innovation for Digital Identity

Digital identity of the objects and the evolution of the PKI in the IoTs
IoT is booming. There will be tens of billion devices connected to the internet by 2020 while several trillion of dollars will be spent on IoT solutions, ranging from smart metering, smart home platforms, vehicle-to-grid hubs, power plant automation, demand-response schemas. Trust in IoT is much more critical than in traditional digital transactions. Trust between objects is fundamental to ensure Identity Proof, Privacy and a clear Liability Framework.
PKI Infrastructures are an established and reliable model to state person and server Identity, and recently became part of the standard in an important area, such as IOT in power production plants.
Can this model be extended in a world with a different cardinality of objects? Do we need to rethink centralized and hierarchical model? Can PKI live together with distributed ledger and different encryption types in a quickly evolving and mostly deregulated scenario? We are working to depict the upcoming IoT trust models, and we think that raising questions to scientific community is a good way to start.

Born in Milan in 1966, married, two children. After a scientific training at the Faculty of Physics in Milan, he began his experience in the world of IT consulting as a freelancer. In the following years he was a founding member of two technology consulting firms in the Groupware and Enterprise Web Development fields. After an experience in DedaGroup as Solution Manager, he started as CTO a new company, Klever, building a strong expertise in regulated ECM solutions. After Klever acquisition by InfoCert, he become Enterprise Solutions Marketing Manager. Currently, he is Head of Product Innovation at InfoCert.

Data Security and Privacy in Emerging Scenarios
The rapid advancements in Information and Communication Technologies (ICTs) have been greatly changing our society, with clear societal and economic benefits. Mobile echnology, Cloud, Big Data, Internet of things, services and technologies that are becoming more and more pervasive and convenientlyaccessible, towards to the realization of a 'smart' society'. At the heart of this evolution is the ability to collect, analyze, process and share an ever increasing amount of data, to extract knowledge for offering personalized and advanced services. A major concern, and potential obstacle, towards the full realization of such evolution is represented by security and privacy issues. As a matter of fact, the (actual or perceived) loss of control over data and potential compromise of their confidentiality can have a strong detrimental impact on the realization of an open framework for enabling collection, processing, and sharing of data, typically stored or processed by external cloud services.
In this talk, I will illustrate some security and privacy issues arising in emerging scenarios, focusing in particular on the problem of managing data while guaranteeing confidentiality and integrity of data stored or processed by external providers.

Pierangela Samarati is a Professor at the Department of Computer Science of the Universita' degli Studi di Milano, Italy. Her main research interests are on data and applications security and privacy, especially in emerging scenarios. She has participated in several projects involving different aspects of information protection. On these topics, she has published more than 260 peer-reviewed articles in international journals, conference proceedings, and book chapters.
She has been Computer Scientist in the Computer Science Laboratory at SRI, CA (USA). She has been a visiting researcher at the Computer Science Department of Stanford University, CA (USA), and at the Center for Secure Information Systems of George Mason University, VA (USA).
She is the chair of the IEEE Systems Council Technical Committee on Security and Privacy in Complex Information Systems (TCSPCIS), of the ERCIM Security and Trust Management Working Group (STM), and of the ACM Workshop on Privacy in the Electronic Society (WPES).She is a member of several steering committees. She is ACM Distinguished Scientist (named 2009) and IEEE Fellow (named 2012).
She has received the IEEE Computer Society Technical Achievement Award (2016). She has been awarded the ESORICS Outstanding Research Award (2018), the IFIP TC11 Kristian Beckman Award (2008), and the IFIP WG 11.3 Outstanding Research Contributions Award (2012).
She has served as General Chair, Program Chair, and program committee member of several international conferences and workshops.

Delayed-Input Cryptographic Protocols
This talk will illustrate the benefits of running a cryptographic protocol when the input is required only in the last round. In particular the talk will consider the use of zero-knowledge proofs for protecting private data stored in a blockchain and will overview the impact of delaying the input in such applications.

Ivan Visconti is an associate professor of Computer and Electrical Engineering and Applied Mathematics Department of the University of Salerno. His main research topics are Cybersecurity and Blockchain Technology. He's the scientific coordinator for University of Salerno of the H2020 European project "PRIViLEDGE" (Privacy-Enhancing Cryptography in Distributed Ledgers), that focuses on Blockchain technology.
