Abstract

Aiming at the problems that the Raft algorithm cannot resist the attacks of Byzantine nodes and the logs are easy to tamper with, this paper proposed a RB-Raft algorithm that resisted Byzantine nodes. Firstly, this paper used the method of hash chain to iteratively hash each log. At the same time, it verificated the log through the dynamic verification mechanism, so that the malicious behavior of the leader node had a certain fault tolerance rate, which solved the problem of log forgery and verification. Secondly, this paper proposed a legacy mechanism based on threshold encryption, which made it legal for candidate nodes to pull votes. This mechanism could prevent Byzantine nodes from randomly the attack of pulling votes to replace leader nodes, and solved the problem that Byzantine nodes affect the system consistency. The experimental results show that the proposed RB-Raft algorithm has the ability to resist Byzantine nodes, and its log recognition rate can reach 100%. At the same time, compared with PBFT, the consensus latency of the algorithm in this paper is reduced by 53.3%, and the throughput is increased by 61.8%. The proposed algorithm is suitable for consensus in untrusted consortium chains.
