Developing a Security Schema for Transparent Groups on a Peer-to-Peer Distributed Database System

Abstract / Excerpt:

In a Peer-to-Peer Distributed Database System (PDBS), peers in a network have their own local databases, and peers share these databases to other peers through user queries. As a fully decentralized Peer-to-Peer distributed database information sharing application, each peer has both the client and the server functions. The server component includes the query service and the schema service, while the client component includes the user interface and client controller. Although PDBS is a reliable system for data sharing, it has minimal mode of security. The system can broadcast advertisements or queries to all peers connected to the network, even if the intention was for a single one. Likewise, if a querying peer does not trust some of its peers in its peer group, since there is no private grouping, even those peers that cannot be trusted will receive the query sent by the querying peer. This study presents a methodology for developing a security schema for transparent groups in a Peer-to-Peer Distributed Database System based on the type of authentication, the trust model, and the threat model to protect peer groups.
