Center for Digital Trust

Center for Digital Trust

"The Cambridge Analytica scandal, the WannaCry hijacking, the hacking of 1 billion Yahoo accounts,…

How much do you trust our digital infrastructure?"

Trust is indispensable to the prosperity and well-being of societies. For millennia, we developed trust-building mechanisms to facilitate interactions. But as they become increasingly digital, many traditional mechanisms no longer function well, hence trust breaks down.

As a result, low levels of trust discourage us from engaging in new forms of interactions and constrain business opportunities.

We must therefore re-invent trust mechanisms that will contribute to prosperous and peaceful societies in the digital age.

Workshop on Security and Privacy of Wearable Devices

27 November 2018

A growing number of wearable devices are becoming available. By their ability to measure physical activity and physiological characteristics such as heart rate, blood pressure, sleep patterns, etc., they constitute a cornerstone for the quantified self and personalized health. Yet, unavoidably, they bring a number of challenges in terms of security and privacy.

This workshop will be held on Thursday, 6 December from 10:15-13:00, in room BC 410 at the EPFL.

EPFL School Assembly Election Secured by DTOP Blockchain

22 June 2018

C4DT's blockchain-based e-voting technology just passed its first real test "with flying colors" during the elections of EPFL's school assembly. The innovative DTOP technology called "cothority" demonstrated that it could be trusted by the technologically demanding EPFL community.

Developed by Professor Ford's DEDIS team, cothority enabled the certification of the election by distinct nodes, operated independently by different school bodies.

What is DTOP?

The DTOP is a set of software libraries for building and testing secure and trustworthy applications. At first, it will integrate three technological pillars into a unified platform.

Privacy Protection and Cryptography: privacy “leakage” protection and security for shared data or analytics.
Blockchains and Smart Contracts: high-performance, feature-rich and secure blockchains, and smart contracts.
Software Verification: automatic verification of software properties and identification of attack scenarios.

The DTOP is also the starting point for the exploration of digital-trust applications in many domains:

Finance: The financial analysis of cryptocurrencies and smart contracts influence their technological development.
Health: Privacy protection for data in personalized medicine helps engage patients and respond to regulations.
Democracy and Humanitarian Assistance: Technologies for e-voting and “smart” services implements democratic and humanitarian values.
Critical Infrastructures: Systemic security models secure energy grids and transportation infrastructures.
Digital Information: Technologies manage digital rights and identify faked images, videos, messages, etc.

The DTOP is also an opportunity to explore the Governance and Ethics challenges of digital trust.
