    ATM cell encryption and key update synchronization

    This paper presents a data compaction/randomization based approach as a mode of block encryption for ATM (Asynchronous Transfer Mode) cells. The presented approach converts a plaintext into pseudo‐random plain...

    Necessary and sufficient conditions on information for causal message ordering and their optimal implementation

    This paper formulates necessary and sufficient conditions on the information required for enforcing causal ordering in a distributed system with asynchronous communication. The paper then presents an algorith...

    Causality and atomicity in distributed computations

    In a distributed system, high-level actions can be modeled by nonatomic events. This paper proposes causality relations between distributed nonatomic events and provides efficient testing conditions for the r...

    The power of logical clock abstractions

    Vector and matrix clocks are extensively used in asynchronous distributed systems. This paper asks, “how does the clock abstraction generalize?” To address this problem, the paper motivates and proposes logica...
