Another Look at Byzantine Fault Tolerance
cryptographic protocols Byzantine Fault Tolerance
2019/7/26
We review several solutions for the Byzantine Fault Tolerance (BFT) problem and discuss some aspects that are frequently overlooked by existing literatures. For example, PBFT and HotStuff BFT protocol...
Introducing Fault Tolerance into Threshold Password-Authenticated Key Exchange
password authentication key exchange fault tolerance
2016/1/23
A threshold password-authenticated key exchange (T-PAKE) protocol allows a set of n servers to collectively authenticate a client with a human-memorizable password such that any subset of size great...
Privacy-Preserving Stream Aggregation with Fault Tolerance
Differential Privacy Periodic Aggregation Untrusted Aggregator Fault Tolerance
2012/6/14
We consider applications where an untrusted aggregator would like to collect privacy sensitive data from users, and compute aggregate statistics periodically. For example, imagine a smart grid operato...
