Preserving Peer Replicas By Rate-Limited Sampled Voting in LOCKSS [article]

Petros Maniatis, Mema Roussopoulos, TJ Giuli, David S. H. Rosenthal, Mary Baker, Yanto Muliadi
2003 arXiv   pre-print
The LOCKSS project has developed and deployed in a world-wide test a peer-to-peer system for preserving access to journals and other archival information published on the Web.  ...  It consists of a large number of independent, low-cost, persistent web caches that cooperate to detect and repair damage to their content by voting in "opinion polls."  ...  In particular, we would like to express our gratitude to Cynthia Dwork, Kevin Lai, Aris Gionis, Katerina Argyraki, Lada Adamic, Sergio Marti, Ed Swierk, Hector Garcia-Molina, and the LOCKSS engineering  ...

Attrition Defenses for a Peer-to-Peer Digital Preservation System [article]

T.J. Giuli, Petros Maniatis, Mary Baker, David S. H. Rosenthal, Mema Roussopoulos
2004 arXiv   pre-print
We describe several defenses for LOCKSS, a peer-to-peer digital preservation system, that help ensure that application-level attacks even from powerful adversaries are less effective than simple network-level  ...  In peer-to-peer systems, attrition attacks include both traditional, network-level denial of service attacks as well as application-level attacks in which malign peers conspire to waste loyal peers' resources  ...  In prior work [29] we used redundancy and rate limitation to defend LOCKSS peers against attacks seeking to corrupt their content.  ...

Conservation vs. Consensus in Peer-to-Peer Preservation Systems [chapter]

Prashanth P. Bungale, Geoffrey Goodell, Mema Roussopoulos
2005 Lecture Notes in Computer Science  
We highlight the design tradeoffs involved in using the two general approaches, and we provide a framework for analyzing the characteristics of peer-to-peer preservation systems in general.  ...  We identify two basic approaches to address the problem of digital preservation using peerto-peer systems: conservation and consensus.  ...  First, it removes those peers that voted in the poll so that the next poll is based on a different sample of peers.  ...

LOCKSS (Lots Of Copies Keep Stuff Safe ) is a prototype of a system to preserve access to scientific journals published on the Web.  ...  It is a majority-voting fault-tolerant system that, unlike normal systems, has far more replicas than would be required just to survive the anticipated failures.  ...  The project was to a large extent inspired by Danny Hillis & Stewart Brand's Millennium Clock project [clock] .  ...

Impeding attrition attacks in P2P systems

Petros Maniatis, TJ Giuli, Mema Roussopoulos, David S. H. Rosenthal, Mary Baker
2004 Proceedings of the 11th workshop on ACM SIGOPS European workshop: beyond the PC - EW11  
We illustrate the application of these defenses in the context of the LOCKSS digital preservation system. 1  ...  These include a spectrum of denial-of-service, or attrition, attacks from low-level packet flooding to high-level abuse of the peer communication protocol.  ...  Rate Limitation: Peers interact with each other by requesting and supplying votes. A peer decides autonomously when to call a poll and from which peers to request votes, based on a fixed target rate.  ...

Efficient cooperative backup with decentralized trust management

Nguyen Tran, Frank Chiang, Jinyang Li
2012 ACM Transactions on Storage  
A high bandwidth node might be limited by its available disk space.  ...  Existing backup systems are unsatisfactory: commercial backup services are reliable but expensive while peer-to-peer systems are cheap but offer limited assurance of data reliability.  ...  For example, LOCKSS [Maniatis et al. 2005 ], a peer-to-peer digital preservation system, uses a friend list to bias weights for different peers' votes.  ...
