Abstract

We revisit the problem of preserving causality in Byzantine fault-tolerant (BFT) atomic broadcast protocols, a requirement first proposed by Reiter and Birman (TOPLAS 1994). While over the past three decades, this requirement has been met through the deployment of expensive public-key threshold cryptosystems, we propose three novel, secure causal BFT protocols without using public-key cryptography. We implement and evaluate these protocols, showing that they significantly outperform existing constructions that use threshold cryptosystems.
安全因果原子广播,重访
我们重新审视了拜占庭容错(BFT)原子广播协议中保留因果关系的问题,这是Reiter和Birman (TOPLAS 1994)首先提出的要求。虽然在过去的三十年中,这一要求已经通过部署昂贵的公钥阈值密码系统来满足,但我们提出了三种新的、安全的因果BFT协议,而不使用公钥加密。我们实现并评估了这些协议,表明它们明显优于使用阈值密码系统的现有结构。
