Exploring Adaptive Byzantine Quorum Systems to Improve Latency in the WAN
Linus Gnan, Rüdiger Kapitza, Christian Berger
Quorum systems enforce strict consistency in Byzantine fault-tolerant (BFT) state machine replication: Before a value is decided, a subset of replicas (called quorum) must exchange…
SoK: Scalability Techniques for BFT Consensus
Christian Berger, Signe Schwarz-Rüsch, Arne Vogel +4
With the advancement of blockchain systems, many recent research works have proposed distributed ledger technology~(DLT) that employs Byzantine fault-tolerant~(BFT) consensus proto…
SplitBFT: Improving Byzantine Fault Tolerance Safety Using Trusted Compartments
Ines Messadi, Markus Horst Becker, Kai Bleeke +3
Byzantine fault-tolerant agreement (BFT) in a partially synchronous system usually requires 3f + 1 nodes to tolerate f faulty replicas. Due to their high throughput and finality pr…
Hector: Using Untrusted Browsers to Provision Web Applications
David Goltzsche, Tim Siebels, Lennard Golsch +1
Web applications are on the rise and rapidly evolve into more and more mature replacements for their native counterparts. This disruptive trend is mainly driven by the attainment o…
Blockchain and Trusted Computing: Problems, Pitfalls, and a Solution for Hyperledger Fabric
Marcus Brandenburger, Christian Cachin, Rüdiger Kapitza +1
A smart contract on a blockchain cannot keep a secret because its data is replicated on all nodes in a network. To remedy this problem, it has been suggested to combine blockchains…
CYCLOSA: Decentralizing Private Web Search Through SGX-Based Browser Extensions
Rafael Pires, David Goltzsche, Sonia Ben Mokhtar +6
By regularly querying Web search engines, users (unconsciously) disclose large amounts of their personal data as part of their search queries, among which some might reveal sensiti…
Rollback and Forking Detection for Trusted Execution Environments using Lightweight Collective Memory
Marcus Brandenburger, Christian Cachin, Matthias Lorenz +1
Novel hardware-aided trusted execution environments, as provided by Intel's Software Guard Extensions (SGX), enable to execute applications in a secure context that enforces confid…
