Analysis and Improvements of the Sender Keys Protocol for Group Messaging
Messaging between two parties and in the group setting has enjoyed widespread attention both in practice, and, more recently, from the cryptographic community. One of the main challenges in the area is constructing secure (end-to- end encrypted) and effici ...
2022Trust as a Programming Primitive
Programming has changed; programming languages have not.Modern software embraced reusable software components, i.e., public libraries, and runs in the cloud, on machines that co-locate applications from various origins.This new programming paradigm leads t ...
EPFL2021SafetyPin: Encrypted Backups with Human-Memorable Secrets
Henry Nathaniel Corrigan-Gibbs
We present the design and implementation of SafetyPin, a system for encrypted mobile-device backups. Like existing cloud-based mobile-backup systems, including those of Apple and Google, SafetyPin requires users to remember only a short PIN and defends aga ...

USENIX ASSOC2020SBFT: a Scalable and Decentralized Trust Infrastructure
SBFT is a state of the art Byzantine fault tolerant state machine replication system that addresses the challenges of scalability, decentralization and global geo-replication. SBFT is optimized for decentralization and is experimentally evaluated on a depl ...
IEEE COMPUTER SOC2019BioID: a Privacy-Friendly Identity Document
Serge Vaudenay, Muhammed Fatih Balli, Fatma Betül Durak
We design a suite of protocols so that a small tamper-resistant device can be used as a biometric identity document which can be scanned by authorized terminals. We target both strongly secure identification and strong privacy. Unlike biometric passports, ...

SPRINGER INTERNATIONAL PUBLISHING AG2019On the Security of Two-Round Multi-Signatures
Bryan Alexander Ford, Manu Drijvers
A multi-signature scheme allows a group of signers to collaboratively sign a message, creating a single signature that convinces a verifier that every individual signer approved the message. The increased interest in technologies to decentralize trust has ...
