F-PKI: Enabling Innovation and Trust Flexibility in the HTTPS Public-Key Infrastructure
Laurent Chuat, Cyrill Krähenbühl, Prateek Mittal +1
We present F-PKI, an enhancement to the HTTPS public-key infrastructure (or web PKI) that gives trust flexibility to both clients and domain owners, and enables certification autho…
A Formally Verified Protocol for Log Replication with Byzantine Fault Tolerance
Joel Wanner, Laurent Chuat, Adrian Perrig
Byzantine fault tolerant protocols enable state replication in the presence of crashed, malfunctioning, or actively malicious processes. Designing such protocols without the assist…
Zero-Knowledge User Authentication: An Old Idea Whose Time Has Come
Laurent Chuat, Sarah Plocher, Adrian Perrig
User authentication can rely on various factors (e.g., a password, a cryptographic key, biometric data) but should not reveal any secret or private information. This seemingly para…
SoK: Delegation and Revocation, the Missing Links in the Web's Chain of Trust
Laurent Chuat, AbdelRahman Abdou, Ralf Sasse +3
The ability to quickly revoke a compromised key is critical to the security of any public-key infrastructure. Regrettably, most traditional certificate revocation schemes suffer fr…
BlockPKI: An Automated, Resilient, and Transparent Public-Key Infrastructure
Lukasz Dykcik, Laurent Chuat, Pawel Szalachowski +1
This paper describes BlockPKI, a blockchain-based public-key infrastructure that enables an automated, resilient, and transparent issuance of digital certificates. Our goal is to a…
Deadline-Aware Multipath Communication: An Optimization Problem
Laurent Chuat, Adrian Perrig, Yih-Chun Hu
Multipath communication not only allows improved throughput but can also be used to leverage different path characteristics to best fulfill each application's objective. In particu…
RITM: Revocation in the Middle
Pawel Szalachowski, Laurent Chuat, Taeho Lee +1
Although TLS is used on a daily basis by many critical applications, the public-key infrastructure that it relies on still lacks an adequate revocation mechanism. An ideal revocati…
PKI Safety Net (PKISN): Addressing the Too-Big-to-Be-Revoked Problem of the TLS Ecosystem
Pawel Szalachowski, Laurent Chuat, Adrian Perrig
In a public-key infrastructure (PKI), clients must have an efficient and secure way to determine whether a certificate was revoked (by an entity considered as legitimate to do so),…
Efficient Gossip Protocols for Verifying the Consistency of Certificate Logs
Laurent Chuat, Pawel Szalachowski, Adrian Perrig +2
The level of trust accorded to certification authorities has been decreasing over the last few years as several cases of misbehavior and compromise have been observed. Log-based ap…
