Convergence and standardisation of different radio communication technologies in 5G and beyond 5G networks has contributed to a surge in smart device usage. With its ever-increasing integration to human lifestyle use of Multi-Hop networks usage is widespread.
Availability of numerous smart devices within very close proximity drives a good interest towards Multi-Hop connectivity. However, the very characteristics such as infrastructure-less nature and ability to self-configure, which elevate them as a top alternative to conventional infrastructure-based network connectivity, expose them for security compromises. Thus, Multi-Hop network security opens a wide research interest.
Threshold-based secret sharing schemes for securing Multi-Hop is the most widely researched in contemporary academia. These researches are conceived on prominent mathematical principals such as univariate polynomial, binomial polynomial, Chinese Remainder Theorem, etc.
This research is to design and optimise a secure routing protocol for Multi-Hop hybrid (5G, Wifi, MANET) networks based on threshold cryptography. This involves devising the application-layer key management protocol, designing the secure routing protocol based on an extension of OLSR. Finally, implement and evaluate the protocol by simulating in NS-3, and a real-time testbed on smart devices.
