There is a big gap between the so-called NISQ (noisy intermediate-scale quantum) and FTQ (fault-tolerant quantum) computing. Recently, we introduced QEQ (quasi-exact quantum) computing, which lies in ...
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...
Generalized Measures of Edge Fault Tolerance in (n,k)-star Graphs
Combinatorics fault-tolerant analysis (n, k)-star graphs edge-connectivity h-super edge-connectivity
2012/4/18
This paper considers a kind of generalized measure $\lambda_s^{(h)}$ of fault tolerance in the $(n,k)$-star graph $S_{n,k}$ for $2\leqslant k \leqslant n-1$ and $0\leqslant h \leqslant n-k$, and deter...
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...
