چکیده
This paper describes the support provided for mobility and fault tolerance in Mykil, which a key distribution protocol for large, secure group multicast. Mykil is based on a combination of group-based hierarchy and key-based hierarchy systems for group key management. Important advantages of Mykil include a fast and efficient rekeying operation for large group sizes, continuous availability of the key management service in a disconnected network environment, an ability to map group structure to the underlying network infrastructure, fault tolerance, and support for member mobility and smaller hand-held devices. Mobility support in Mykil allows mobile group members to access a multicast service without any need for going through an extensive registration process. Fault tolerance support allows group members to access a multicast service despite communication failures, network partitions, and node failures in the network. A prototype of Mykil has been implemented. The paper describes this implementation and reports on the performance measured from this implementation.

Abstract Using mobile agents, it is possible to bring the code close to the resources, which is not foreseen by the traditional client/server paradigm. Compared to the client/server computing paradigm, the greater flexibility of the mobile agent paradigm comes at additional costs as well as the additional complexity of developing and managing mobile agent-based applications. Such complexity ...
متن کاملBatch Rekeying in Mykil Key Management System
This paper describes support for batch rekeying in Mykil, a key management system for supporting secure group multicast. Batch rekeying in Mykil allows for substantial reductions in the cost and complexity of rekeying operations, arguably the expensive portion of the system. By accumulating join and leave operations and utilizing an algorithmic approach to minimize the number of necessary rekey...

Stability Assessment Metamorphic Approach (SAMA) for Effective Scheduling based on Fault Tolerance in Computational Grid
Grid Computing allows coordinated and controlled resource sharing and problem solving in multi-institutional, dynamic virtual organizations. Moreover, fault tolerance and task scheduling is an important issue for large scale computational grid because of its unreliable nature of grid resources. Commonly exploited techniques to realize fault tolerance is periodic Checkpointing that periodically ...
