| 摘 要： | 针对当前对等网中虚假文件的问题,提出了一种安全P2P共享模型(SPSM)。在该模型中为了激励节点共享自己的资源,引入虚拟货币(VC)以激励各个节点共享自己的资源;并在模型中引入了举报机制,即当网络中一个节点下载了虚假文件后就向CA(Certification Authorities,认证中心)举报提供虚假资源的节点,经CA甄别后将该恶意节点放入恶意节点集;为了节省存储空间,SPSM根据自身的特点,采用了Bloom Filter的变体DBF来存储恶意节点。为了验证提出的SPSM模型的有效性,将其与Trust模型进行了比较,结果表明SPSM模型比Trust模型更有效。

| Abstract: | To resolve the problem of inauthentic files,this paper proposed a security P2P sharing model(SPSM).To incentive all the nodes sharing its resources,this paper introduced virtual currencies in SPSM;and introduced a prosecutive rules in SPSM,that is some nodes would prosecute a node which uploaded an inauthentic files,then CA(certification authorities) would put the malicious node into malicious sets when validating the identity of malicious node,to save the storage spaces,and considing the character of SPSM,... |
