对等云存储系统信誉机制研究
A reputation mechanism in peer-to-peer cloud storage systems
摘要
Abstract
As the latest development of the distributed storage technology,cloud storage is a product of the integration of distributed storage and virtualization technologies.Cloud storage allows use to storage facilities available on the internet.Relative to the current Master/Slave computing model cloud storage file systems,including GFS,HDFS,Sector and KFS,an open P2P（peer-to-peer） cloud storage system based on DHT was proposed,and we constructed a prototype system named MingCloud based on the Kademlia algorithm.According to the research-development needs of the system,a reputation mechanism was designed for the system,specifically including the calculation of reputation degree,trust model design,work process of reputation mechanism,and safety analysis.Our simulation results show that the mechanism of this model provides a high degree of effectiveness and robustness.Meanwhile,the reputation model can effectively protect honest nodes,reduce the trust value of malicious nodes,and restrain malicious behaviors.关键词
