The core problem in risk analysis - determining exploitable paths between attackers and system assets is essentially a problem of determining information flow. It is relatively st...
Using certificates for distributed authorizations in computer network systems has been discussed in the literature. However real implementations of the concept are rarely seen. In...
Abstract. Grids are very complex and volatile infrastructures that exhibit parallel and distributed characteristics. To harness their complexity as well as the increasing intricacy...
Peer-to-peer (P2P) networks based on consistent hashing functions have an inherent load uneven distribution problem. Things are even worse in unstructured P2P systems. The objecti...
or fault-tolerant asynchronous systems. It abstracts a family of problems known as Agreement (or Coordination) problems. Any solution to consensus can serve as a basic building blo...
