Randomized agreement protocols have been around for more than two decades. Often assumed to be inefficient due to their high expected communication and time complexities, they ha...

The Amoeba group communication system has two unique aspects: (1) it uses a sequencer-based protocol with negative acknowledgements for achieving a total order on all group messag...
Authentication and key distribution protocols that utilize weak secrets (such as passwords and PINs) are traditionally susceptible to guessing attacks whereby an adversary iterate...
We propose an improved probabilistic method for reading remote clocks in systems subject to unbounded communication delays and use this method to design a family of fault-tolerant...
The paper presents a fail-safe mobility management and a collision prevention platform for a group of asynchronous cooperative mobile robots. The fail-safe platform consists of a ...
