基于区块链的P2P节点信任评价模型
|
摘要
由于P2P网络去中心化特性,导致无法直接使用传统集中式网络的节点信用评价指标。为了得到可信的数据,融合hash链的帕特里夏树和电商行业区块链,通过对经典模型的剖析,给出了较为完善的信用指标体系,引入节点信用指标的时间敏感函数,构建节点信任评价模型,并进行了效能分析。通过分析表明,该模型能保证P2P网络数据安全性。
As a result of the decentration of P2 P network,node credit evaluation indexes of traditional centralized network can not be directly used. In order to obtain credible data,the Patricia tree and SEC Blockchain are integrated with the hash chain. Through the analysis of the classical model,a more complete credit index system is proposed. The time-sensitive function of node credit is introduced to construct the node trust evaluation model,and the efficiency analysis is also carried out. The analysis shows that this model can guarantee the data security of P2 P network.
