Secure, Highly Available, and High Performance Peer-to-Peer Storage Systems
Storage system is an important component in many data intensive applications, including data grid. Security,availability, and high performance are important issues in the storage system design. In this paper we present a Peer-to-Peer (P2P) storage system design based on distributed hash table (DHT) and short secret sharing (SSS)to provide highly available, secure and efficient data storage services. Existing DHTs do not consider share location and search. Also, storage systems using data partitioning schemes (including SSS) does not consider the severe problems in share update. We develop three access protocols to maintain the share consistency in spite of concurrent update, partial update and compromised storage nodes by storing a limit number of history versions of the shares. We also conducted experimental studies to evaluate the performance and data availability and compare the behaviors of the schemes.
