In this work, we make utilization of users' computers involved in this distributed storage system easily, and share their powerful resources with this P2P environment. Users can download the files from this P2P distributed storage system. To transfer more efficiently, this paper also proposes a parallel transfer algorithm for every node and replication mechanism. The experiment results have shown it is an effective parallel transfer method, which not only use network bandwidth more, but also reduce the download transfer time.
RFID security protocol is widely discussed as an important issue, while the mutual authentication with the security agreement is mostly discussed enthusiastically. In this paper we improve HB family to achieve the property of mutual authentication, so that the user privacy can be protected. The future direction is to adapt the protocol for cloud computing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
