Does Proactive Secret Sharing Perform in Peer-to-Peer Systems?

Authors: Nicolas C. Liebau, Andreas U. Mauthe, Vasilios Darlagiannis, and Ralf Steinmetz

Published in: OASIcs, Volume 17, 17th GI/ITG Conference on Communication in Distributed Systems (KiVS 2011)

Abstract

Trustworthy applications in fully decentralized systems require a trust anchor. This paper describes how such an anchor can be implemented efficiently in p2p systems. The basic concept is to use threshold cryptography in order to sign messages by a quorum of peers. The focus is put on advanced mechanisms to secure the shares of the secret key over time, using proactive secret sharing. This mechanism was researched in context of the token-based accounting scheme.
