Adaptive Rekeying for Secure Multicast∗
In this paper, we focus on the problem of secure multicast in dynamic groups. In this problem, a group of users communicate using a shared group key. Due to the dynamic nature of these groups, to preserve secrecy, it is necessary to change the group key whenever the group membership changes. While the group key is being changed, the group communication needs to be interrupted until the rekeying...
متن کاملAn Adaptive Hybrid Rekeying Protocol for Dynamic Multicast Groups
In secure multi-party communications, the Logical Key Hierarchy scheme has been proved to be communication optimal for large groups. However, this scheme still suffers from an expensive rekeying cost when the group is very dynamic. To reduce the rekeying cost, Zhu et al. suggested to partition the logical key tree in two sub-trees based on the duration of each member in the multicast group. Alt...
متن کاملDistributed Multicast Group Security Architecture
Multicast communication is an efficient means to support key network applications such as real-time teleconferencing and data dissemination. In this paper we devise a security architecture for multicast communications in mobile ad hoc networks (MANETs). Our design is both suitable in MANET environment and compliant to the IETF standard Multicast Group Security Architecture (MGSA) [1]. Because c...
متن کاملAn Efficient Rekeying Function Protocol with Multicast Key Distribution for Group Key Management in MANETs
Key management in the ad hoc network is a challenging issue concerning the security of the group communication. Group key management protocols can be approximately categorized into three: centralized, decentralized, and distributed. The much apt solution to provide the services like authentication, data integrity and data confidentiality is the establishment of a key management protocol. This p...
متن کاملA Scalable and Reliable Key Distribution Protocol for Multicast Group Rekeying
Scalable group rekeying is one of the important problems that needs to be addressed in order to support secure communications for large and dynamic groups. One of the challenging issues that arises in scalable group rekeying is the problem of delivering the updated keys to the members of the group in a reliable and timely manner. In this paper, we present a new scalable and reliable key distrib...
