An Investigation of Group Key Management with Mobility Protocol for 5G Wireless Mobile Environment. A Case analysis of group key management security requirements with respect to wireless mobile environment of different proposed solutionsEya, Nnabuike N. January 2019 (has links)
Group communication, security and 5G technology present a unique dimension
of challenges and security remains crucial in the successful deployment of 5G
technology across different industry. Group key management plays a vital role in
secure group communication.
This research work studies various group key management schemes for mobile
wireless technology and then a new scheme is proposed and evaluated. The
main architecture is analysed, while the components and their roles are
established, trust and keying relationships are evaluated, as well as detailed
functional requirements.
A detailed description of the main protocols required within the scheme is also
described. A numerical and simulation analysis is employed to assess the
proposed scheme with regards to fulfilling the security requirement and
performance requirements. The impact of group size variation, the impact of
mobility rate variation are studied with regards to the average rekeying messages
induced by each event and 1-affects-n phenomenon.
The results obtained from the simulation experiments show that the proposed
scheme outperformed other solutions with a minimal number of rekeying
messages sent and less number of affected members on each event. The
security requirements demonstrate that backward and forward secrecy is
preserved and maintained during mobility between areas.
Finally, the research work also proposes a 5G-enabled software-defined
multicast network (5G-SDMNs), where software-defined networking (SDN) is
exploited to dynamically manage multicast groups in 5G and mobile multicast
environment. Also, mobile edge computing (MEC) is exploited to strengthen
network control of 5G-SDMN. / National Open University of Nigeria
