Framework of Multiparty Computation for Higher Non-Repudiation in Internet-of-Things (IoT)

– Multiparty computation is essential in offering a better form of non-repudiation, which is not much explored in past research work. A review of existing non-repudiation-based approaches found various shortcomings that do not offer a good balance between robust security and algorithm efficiency. Therefore, the proposed study presents a novel yet simple multiparty computation framework to ensure a higher degree of non-repudiation considering a use-case of a highly distributed and large network, i.e., Internet-of-Things (IoT). The study implements a unique encryption mechanism that uses a transformation strategy to perform encoding while using split key management to retain maximal secrecy and multiparty authentication for enhanced security. The simulation outcome of the study showcases that the proposed scheme offers approximately a 48% reduction in computation overhead, 54% minimization in delay, and 58% faster processing in contrast to frequently reported non-repudiation schemes.
