The eBPF Runtime in the Linux Kernel
Bolaji Gbadamosi, Luigi Leonardi, Tobias Pulls +4
Extended Berkeley Packet Filter (eBPF) is a runtime that enables users to load programs into the operating system (OS) kernel, like Linux or Windows, and execute them safely and ef…
Maybenot: A Framework for Traffic Analysis Defenses
Tobias Pulls, Ethan Witwer
End-to-end encryption is a powerful tool for protecting the privacy of Internet users. Together with the increasing use of technologies such as Tor, VPNs, and encrypted messaging,…
Towards Effective and Efficient Padding Machines for Tor
Tobias Pulls
Tor recently integrated a circuit padding framework for creating padding machines: defenses that work by defining state machines that inject dummy traffic to protect against traffi…
Aggregation-Based Certificate Transparency Gossip
Rasmus Dahlberg, Tobias Pulls, Jonathan Vestin +2
Certificate Transparency (CT) requires that every CA-issued TLS certificate must be publicly logged. While a CT log need not be trusted in theory, it relies on the assumption that…
Verifiable Light-Weight Monitoring for Certificate Transparency Logs
Rasmus Dahlberg, Tobias Pulls
Trust in publicly verifiable Certificate Transparency (CT) logs is reduced through cryptography, gossip, auditing, and monitoring. The role of a monitor is to observe each and ever…
The Effect of DNS on Tor's Anonymity
Benjamin Greschbach, Tobias Pulls, Laura M. Roberts +2
Previous attacks that link the sender and receiver of traffic in the Tor network ("correlation attacks") have generally relied on analyzing traffic from TCP connections. The TCP co…
ScrambleSuit: A Polymorph Network Protocol to Circumvent Censorship
Philipp Winter, Tobias Pulls, Juergen Fuss
Deep packet inspection technology became a cornerstone of Internet censorship by facilitating cheap and effective filtering of what censors consider undesired information. Moreover…
