Scientific workflows are a powerful programming technique for specifying complex computations using a number of otherwise independent components. When used in a Grid environment, ...
Abstract. There are many potential users and uses for grid computing. However, the concept of sharing computing resources excites security concerns and, whilst being powerful and f...
Abstract. To overcome increasing complexity and dynamic nature of distributed computing system, such as ubiquitous computing systems, it is critical to have computing systems that ...
Firewalls provide very good network security features. However, classical perimeter firewall deployments suffer from limitations due to complex network topologies and the inabilit...
The Universal Composability framework was introduced by Canetti to study the security of protocols which are concurrently executed with other protocols in a network environment. U...
