Tittel: "Firefly: Scalable Intrusion-Tolerant Membership"
Foredragsholder: Senior research associate Robbert van Renesse, Cornell University, USA.

Abstract:
In this talk I will describe and evaluate Firefly, a scalable and intrusion-tolerant protocol for weakly consistent membership, or more popularly known as a One Hop Distributed Hash Table. While such a protocol cannot distinguish malicious members from correct members in general, it provides correct members with a reasonably current view of which members are live and which are not. The amount of data sent by correct members grows linearly with the aggregate rate of failures and recoveries. Firefly tolerates intrusions in that, with high probability, malicious participants cannot make a correct member look stopped, nor a stopped member look correct, nor cause a correct member to send large amounts of data and render the protocol unscalable.
