Rethinking Block Storage Encryption with Virtual Disks
Danny Harnik, Oded Naor, Effi Ofer +1
Disk encryption today uses standard encryption methods that are length preserving and do not require storing any additional information with an encrypted disk sector. This signific…
Byzantine Agreement with Less Communication: Recent Advances
Shir Cohen, Idit Keidar, Oded Naor
In recent years, Byzantine Agreement is being considered in increasing scales due to the proliferation of blockchains and other decentralized financial technologies. Consequently,…
All You Need is DAG
Idit Keidar, Eleftherios Kokoris-Kogias, Oded Naor +1
We present DAG-Rider, the first asynchronous Byzantine Atomic Broadcast protocol that achieves optimal resilience, optimal amortized communication complexity, and optimal time comp…
Expected Linear Round Synchronization: The Missing Link for Linear Byzantine SMR
Oded Naor, Idit Keidar
State Machine Replication (SMR) solutions often divide time into rounds, with a designated leader driving decisions in each round. Progress is guaranteed once all correct processes…
Cogsworth: Byzantine View Synchronization
Oded Naor, Mathieu Baudet, Dahlia Malkhi +1
Most methods for Byzantine fault tolerance (BFT) in the partial synchrony setting divide the local state of the nodes into views, and the transition from one view to the next dicta…
