IncShrink: Architecting Efficient Outsourced Databases using Incremental MPC and Differential Privacy
Chenghong Wang, Johes Bater, Kartik Nayak +1
In this paper, we consider secure outsourced growing databases that support view-based query answering. These databases allow untrusted servers to privately maintain a materialized…
Classifying Trusted Hardware via Unidirectional Communication
Naama Ben-David, Kartik Nayak
It is well known that Byzantine fault tolerant (BFT) consensus cannot be solved in the classic asynchronous message passing model when one-third or more of the processes may be fau…
DP-Sync: Hiding Update Patterns in Secure Outsourced Databases with Differential Privacy
Chenghong Wang, Johes Bater, Kartik Nayak +1
In this paper, we have introduced a new type of leakage associated with modern encrypted databases called update pattern leakage. We formalize the definition and security model of…
Strengthened Fault Tolerance in Byzantine Fault Tolerant Replication
Zhuolun Xiang, Dahlia Malkhi, Kartik Nayak +1
Byzantine fault tolerant (BFT) state machine replication (SMR) is an important building block for constructing permissioned blockchain systems. In contrast to Nakamoto Consensus wh…
BFT Protocol Forensics
Peiyao Sheng, Gerui Wang, Kartik Nayak +2
Byzantine fault-tolerant (BFT) protocols allow a group of replicas to come to a consensus even when some of the replicas are Byzantine faulty. There exist multiple BFT protocols to…
Byzantine Agreement, Broadcast and State Machine Replication with Near-optimal Good-case Latency
Ittai Abraham, Kartik Nayak, Ling Ren +1
This paper investigates the problem \textit{good-case latency} of Byzantine agreement, broadcast and state machine replication in the synchronous authenticated setting. The good-ca…
