    • The Architecture and Performance of Security Protocols in the EnsembleGroup Communication System 

      Rodeh, Ohad; Birman, Kenneth; Dolev, Danny (Cornell University, 2000-10-17)
      Ensemble is a Group Communication System built at Cornell and the Hebrew universities. It allows processes to create process groups within which scalable reliable fifo-ordered multicast and point-to-point communication are ...
    • Ensemble Security 

      Rodeh, Ohad; Birman, Kenneth P.; Hayden, Mark; Xiao, Zhen; Dolev, Danny (Cornell University, 1998-09)
      Ensemble is a Group Communication System built at Cornell and the Hebrew Universities. It allows processes to create {\it process groups} in which scalable reliable fifo-ordered multicast and point-to-point communication ...
    • The Horus and Ensemble Projects: Accomplishments and Limitations 

      Birman, Kenneth P.; Constable, Robert; Hayden, Mark; Hickey, Jason; Kreitz, Christoph; Van Renesse, Robbert; Rodeh, Ohad; Vogels, Werner (Cornell University, 1999-10)
      The Horus and Ensemble efforts culminated a multi-year Cornell research program in process group communication used for fault-tolerance, security and adaptation. Our intent was to understand the degree to which a single ...
    • Optimized Group Rekey for Group Communications Systems 

      Rodeh, Ohad; Birman, Ken; Dolev, Danny (Cornell University, 1999-08)
      In this paper we describe an efficient algorithm for the management of group keys. Our algorithm is based on a protocol for secure IP-multicast and is used to manage group-keys in group-communications systems. Unlike prior ...
    • A Study of Group Rekeying 

      Rodeh, Ohad; Birman, Kenneth P.; Dolev, Danny (Cornell University, 2000-03-20)
      In this paper we study the key management problem, in the context of Group Communication Systems (GCS). GCSs are mid-sized systems scaling up to 100 members. We present a side-by-side comparison of three ways of managing ...
    • Using AVL Trees for Fault Tolerant Group Key Management 

      Rodeh, Ohad; Birman, Kenneth; Dolev, Danny (Cornell University, 2000-11-02)
      In this paper we describe an efficient algorithm for the management of group-keys for Group Communication Systems. Our algorithm is based on the notion of key-graphs, previously used for managing keys in large IP-multicast ...
