@inproceedings { , title = {A Decentralized Batch-Based Group Key Management Protocol for Mobile Internet of Things (DBGK)}, abstract = {It is anticipated that constrained devices in the Internet of Things (IoT) will often operate in groups to achieve collective monitoring or management tasks. For sensitive and mission-critical sensing tasks, securing multicast applications is therefore highly desirable. To secure group communications, several group key management protocols have been introduced. However, the majority of the proposed solutions are not adapted to the IoT and its strong processing, storage, and energy constraints. In this context, we introduce a novel decentralized and batch-based group key management protocol to secure multicast communications. Our protocol is simple and it reduces the rekeying overhead triggered by membership changes in dynamic and mobile groups and guarantees both backward and forward secrecy. To assess our protocol, we conduct a detailed analysis with respect to its communcation and storage costs. This analysis is validated through simulation to highlight energy gains. The obtained results show that our protocol outperforms its peers with respect to keying overhead and the mobility of members.}, conference = {2015 IEEE International Conference on Computer and Information Technology; Ubiquitous Computing and Communications; Dependable, Autonomic and Secure Computing; Pervasive Intelligence and Computing}, doi = {10.1109/cit/iucc/dasc/picom.2015.166}, isbn = {9781509001545}, organization = {Liverpool, UK}, pages = {1109-1117}, publicationstatus = {Published}, publisher = {Institute of Electrical and Electronics Engineers}, url = {http://researchrepository.napier.ac.uk/id/eprint/9137}, keyword = {004.2 Systems analysis, design & performance, QA76 Computer software, Internet of Things, Centre for Distributed Computing, Networking and Security, AI and Technologies, research and development, computer programming and research, software development, protocils}, year = {2015}, author = {Abdmeziem, Mohammed Riyadh and Tandjaoui, Djamel and Romdhani, Imed} }
