摘　　要：Freenet,又叫自由网,是一种分布式信息存储和搜索系统,设计定位于保障信息的私有性和有效性。系统的运行类似于一个具有位置无关性特征的分布式文件系统,这个文件系统由许多独立的计算机组成,这些计算机允许用户匿名进行文件的插入、存储和请求。在自由网中,发布的匿名性,文件的标识、发布、存储、请求都与自由网的密钥和索引机制有着相当密切的联系,该文对自由网中的密钥机制做了一定程度的分析、探索,以求能对自由网的运行机制的进一步研究和了解有所帮助。Freenet is an adaptive peer-to-peer network application that permits the publication,replication,and retrieval of data while protecting the anonymity of both authors and readers.Freenet operates as a network of identical nodes that collectively pool their storage space to store data files and cooperate to route requests to the most likely physical location of data.The distributed file system including many computery,allows users to insert,storage and request files anonymously.In Freenet,the anonymity of publish,the identification,publish,storage,request of file are very closed with Freenet's key.This paper analyzes the mechanism of key in some extent and has some idea about the process of system.All of these will provide help for the last research of Freetnet.
