Protocol design for scalable and reliable group rekeying
… key after users join and leave (called group rekeying), by composing a rekey message that consists of encrypted new keys (encryptions, in short) and delivering it to all users. When group size is large, it becomes infeasible to rekey per user join or leave because of its high processing and …

A Framework for Secure Group Key Management
… group key manager (GKM) has to perform group rekeying for every join or leave request. Fast rekeying is crucial to an application's performance that has large group size, experiences frequent joins and leaves, or where the GKM is hosted by a group member. Examples of such applications are …

Design and Analysis of QoS-Aware Key Management and Intrusion Detection Protocols for Secure Mobile Group Communications in Wireless Networks
… develop three "threshold-based" periodic batch rekeying protocols to reduce the network communication cost caused by rekeying operations to deal with outsider attacks. Instead of individual rekeying, i.e., performing a rekeying operation right after each group membership change event, these …

A prototype system for geo-based, cryptographically-enforced access control for miniature drones' video feeds
… cryptographically through real-time, in-band rekeying of the authorized devices. This rekeying occurs virtually instantaneously, without any loss in the quality of service for the authorized participants. The proof-of-concept system achieves two goals. First, it serves as a compelling …

Location based authenticated multi-services group key management for cyber security in high speed broadband wireless multicast communications. Multi-service group key management scheme with location based handover authentication for multi-handoffs participating in multi-group service subscriptions, its performance evaluation and security correctness in high speed broadband wireless multicast communications
… significant resource economy in terms of reduced rekeying transmission, communication bandwidth and storage overheads while providing enhanced security. The performance of the SMGKM in a high speed environment is also evaluated and has demonstrated that SMGKM outperforms the previous work. …

Modelling and Evaluation of Performance, Security and Database Management Trade-offs in Cloud Computing Platforms. An investigation into quantitative modelling and simulation analysis of ‘optimal’ performance, security and database management trade-offs in Cloud Computing Platforms (CCPs), based on Stochastic Activity Networks (SANs) and a three-tier combined metrics
… services. Security mechanisms such as: batch rekeying, intrusion detection, encryption/decryption or security protocols come at the expense of performance and computing resources consumption. Furthermore, database management processing also has an adverse effect on performance especially in …
