SG-PBFT: a Secure and Highly Efficient Blockchain PBFT Consensus Algorithm for Internet of Vehicles
CoRR, 2021 The Internet of Vehicles (IoV) is an application of the Internet of things (IoT). It faces two main security problems: (1) the central server of the IoV may not be powerful enough to support the centralized authentication of the rapidly increasing connected vehicles, (2) the IoV itself may not be robust enough to single-node attacks.

Genome-wide identification of the PEBP genes in pears and the putative role of PbFT in flower bud differentiation [PDF]
PeerJ, 2020 Although Phosphatidylethanolamine-binding protein (PEBP) genes have been identified in several plants, little is known about PEBP genes in pears. In this study, a total of 24 PEBP genes were identified, in which 10, 5 and 9 were from Pyrus bretschneideri

An Improved Scheme for PBFT Blockchain Consensus Algorithm Based on Ring Signature [PDF]
Jisuanji gongcheng, 2019 The alliance chain is a kind of blockchain that allows authorized nodes to join in the network.However,when the network condition is poor,the nodes will join and exit dynamically.Therefore,on the basis of ring signature theory,ElGamal digital signature ...

Optimistically Batched PBFT Consensus
In the current technological landscape, a topic of significant interest is Distributed Systems, a concept where a system is built up by separate sub-processes which to the user exhibits a unified front. Due to the fragmented nature of distributed systems, the concept of partial failures exists, where one node in the system may act maliciously and cause
