Multi parameter multilevel (MPML) based Trust Management System for Healthcare

Resounding extension of the cyber physical systems has garnered substantial attention from the scientific community over the last two decades. The infusion of IoT has intricately connected our world, endowing intelligent devices with the finesse to adeptly perform daily tasks. Swift technological progress in this arena foreshadows the continued evolution of diverse smart applications, ranging from intelligent healthcare and homes to futuristic cities. Nevertheless, the surge in interconnected nodes within the expansive IoT network brings forth a formidable scalability concern, given the heterogeneity of nodes with respect to processing capacity, energy expenditure, as well as capacity.Conventional security measures, while crucial, fall short in effectively safeguarding these intricate smart applications. Addressing this exigency, the role of trust becomes paramount in mitigating the vulnerabilities that arise when IoT nodes interlink with the digital realm. Amidst this backdrop, diverse trust models, spanning direct, indirect, and hybrid trust computation methods, have been proposed for trust management. However, these models often grapple with adapting comprehensively to the dynamic and ever-evolving nature of intelligent IoT systems. In response, the proposed system introduces a sophisticated three-tiered approach: Trust Calculation, Propagation, and modification. Centerpiece of the system is a meticulously crafted trust calculation algorithm, bespoke for IoT devices. This algorithm harmoniously integrates considerations of both direct and indirect trust, underpinned by a multi-parameter multilevel trust calculation framework. The overarching aim is to attain the pinnacle of precision in evaluating the trustworthiness intrinsic to this intricate IoT landscape.
