March 28, 2009

INForum 2009Computer and Communications Security Track, Sep 10-11, 2009.

Summary (in portuguese):

O INForum tem como objectivo ser um evento privilegiado de reunião da comunidade nacional nas diversas vertentes da informática e ambiciona ser o fórum de eleição para a divulgação, discussão e reconhecimento de trabalhos científicos. O INForum surge com particular oportunidade como palco para a estreia de jovens investigadores que buscam a divulgação, a crítica construtiva e o encorajamento ao seu trabalho.

O 1º INForum pretende ser abrangente e dinâmico no conjunto de tópicos abordados. Apresentará um conjunto de tópicos propostos e seleccionados anualmente, com sessões organizadas e realizadas de forma independente. Promove-se assim a massa crítica para o fortalecimento e evolução da informática no país criando-se, simultaneamente, espaço à evolução do contexto da conferência e fomentando a reunião de investigadores em áreas emergentes.

O 1º INForum decorrerá nos dias 10 e 11 de Setembro de 2009 na Faculdade de Ciências da Universidade de Lisboa.


DSN 2009 Fast Abstracts

February 28, 2009

DSN 2009: 39th Annual IEEE/IFIP International Conference on Dependable Systems and Networks, June 29 – July 2, 2009.

Summary:

DSN is the chosen forum for researchers around the world, for presenting the very best research results, solutions to problems, and insight into emergent new challenges. DSN has pioneered the fusion between security and dependability, understanding the need to simultaneously fight against cyber attacks, accidental faults, design errors, and unexpected operating conditions.

JBP – Java Byzantine Paxos

December 18, 2008

JBP aims to provide a complete, modular and clear implementation of the Byzantine Paxos agreement protocol in Java programming language. Since there are several variants of this algorithm, we choose to implement Paxos at War, by Piotr Zielinski, for consensus and extended it to for total order multicast adding only one communication step and maintaining the quadratic message complexity using the usual technique proposed by Leslie Lamport in the Classical Paxos algorithm and later extended by Castro and Liskov in the BFT system.

JBP was developed because there was no implementation of a fast Byzantine fault-tolerant Total order multicast protocol in Java. Moreover, JBP implementation follow the same line of the BFT system (implemented in C), but we want to separate state management (basically, checkpoints) from the core total order multicast algorithm.

JBP is available to download, you are welcome to try it!
