Decentralized Access Control in Networked File Systems
The Internet enables global sharing of data across organizational boundaries. Traditional access control mechanisms are intended for one or a small number of machines under common administrative control, and rely on maintaining a centralized database of user identities. They fail to scale to a large user base distributed across multiple organizations. This survey provides a taxonomy of decentra...
متن کاملDecentralized Regulation of Distributed Systems: Beyond Access Control
This paper introduces a model of interaction control for the regulation of distributed systems, which can cope with their increasing openness and heterogeneity. This model goes well beyond conventional access control. It is, in particular, inherently decentralized, and thus scalable even for wide range of stateful policies. And it is very general, and not biased toward any particular type of po...

متن کاملDecentralized Channel Access for Wireless Control Systems
We consider a wireless control architecture where multiple sensors independently and randomly access a shared wireless medium to communicate with corresponding actuators, and we develop a decentralized channel access mechanism. Each sensor iteratively adapts the rate at which it accesses the medium in order to mitigate the effect of packet collisions from simultaneously transmitting sensors on ...
