Dynamic Group Communication Security
I f multicast communication appears as the most eficient way to send data to a group of participants, it presents also more vulnerabilities to attacks and requires services such as authentication, integrity and confidentiality to transport data securely. In this papel; we present the protocol Baal’ as a scalable solution to group key inanagement problems and show how Baal resolves the user’s re...
متن کاملDynamic Authenticated Secure Group Communication
Providing authentication for the messages exchanged between group members in addition to confidentiality is an important issue in Secure Group communication. We develop a protocol for Secure Authentic Communication where we address authentication for the group communication scheme proposed by Blundo et al. which only provides confidentiality. Authentication scheme used is a multiparty authentic...
متن کاملA Dynamic Primary Configuration Group Communication Service
Quorum-based methods for managing replicated data are popular because they provide availability of both reads and writes in the presence of faulty behavior by some sites or communication links. Over a very long time, it may become necessary to alter the quorum system, perhaps because some sites have failed permanently and others have joined the system, or perhaps because users want a diierent t...
متن کاملDynamic Load Balancing with Group Communication
This work considers the problem of efficiently performing a set of tasks using a network of processors in the setting where the network is subject to dynamic reconfigurations, including partitions and merges. A key challenge for this setting is the implementation of dynamic load balancing that reduces the number of tasks that are performed redundantly because of the reconfigurations. We explore...
متن کاملE ects of Delayed Communication in Dynamic Group Formation
We investigate how delayed communication a ects the dynamic formation of groups in distributed systems, where all decision-making agents join the same group because each expects to improve its own performance. For example, distributed job schedulers may form a group to utilize the idle resources of other members within the group. Forming a group is a search problem and we examine agents which u...
