Reactive Key Management Scheme for Access Control in Group Communications
نویسندگان
چکیده
To control various access privileges in group-oriented applications having multiple data streams, we present a novel reactive key management scheme where each member can obtain the key of a data stream from public parameters only when necessary. Compared with the previous schemes, this scheme significantly reduces the amount of rekey messages for dynamic membership change due to its reactive nature. key words: group communication, group security, key management, access control, reactive approach

Efficient group key management for multi-privileged groups
Multi-privileged group communications containing multiple data streams have been studied in the traditional wired network environment and the Internet. With the rapid development of mobile and wireless networks and in particular mobile ad-hoc networks (MANETs), the traditional Internet has been integrated with mobile and wireless networks to form the mobile Internet. The multi-privileged group ...
متن کاملEfficient security mechanisms for overlay multicast based content delivery
This paper studies the security issues that arise in an overlay multicast architecture where service providers distribute content such as web pages, static and streaming multimedia data, realtime stock quotes, or security updates to a large number of users. In particular, two major security problems of overlay multicast, network access control and group key management, are addressed. We first p...
متن کاملAn Overview of Group Key Management Issues in IEEE 802.16e Networks
The computer industry has defined the IEEE 802.16 family of standards that will enable mobile devices to access a broadband network as an alternative to digital subscriber line technology. As the mobile devices join and leave a network, security measures must be taken to ensure the safety of the network against unauthorized usage by encryption and group key management. IEEE 802.16e uses Multica...
متن کاملDistributed Hierarchical Access Control for Secure Group Communications
Hierarchical access control to ensure multiple levels of access privilege for group members is required in many environments, such as hierarchically managed organizations and multimedia applications. In this paper, to efficiently and effectively achieve this goal, we propose a distributed key management scheme whereby each SG (Service Group) maintains an SG server. This server is utilized to ma...
متن کاملComputation Efficient Attribute Based Broadcast Group Key Management for Secure Document Access in Public Cloud
An efficient fine-grained encryption-based access control scheme for documents stored in the public cloud network proposed by Mohamed et al utilizes more computational and storage complexities. Although, Mohamed et al.'s broadcast key management scheme communicates group key securely, it consumes massive computational and storage resources for frequently changing the group key. In order to avoi...
