A comprehensive analysis of IoT security towards providing a cost-effective solution: a layered approach

Abstract: The Internet of Things (IoT) greatly influences people’s lives. Traditional privacy and security mechanisms may not suit for Internet of Things due to its resource constraint environments. So there is a need for privacy and security mechanisms, especially for IoT. A good number of security mechanisms are available in the network and application layers. The study reveals that there should be much more scope for providing security and privacy in the sensing layer itself. The paper focuses on IoT security goals and the security framework at the sensing layer. The sensing layer privacy and security are implemented through Blockchain Technology. The security is transmitted to the top layers, such as the network and application layers, by safeguarding the sensing layer. The cost of the highest tiers of security is automatically reduced. Then we analysed the proposed framework concerning security attacks and security goals. Finally, we analysed the cost-effectiveness of the system. Also, with the proposed work, 57.41% of IoT security goals impacts are reduced. At the physical layer, 71.43%; at the network layer, 70.59% and at the application layer, 38.46% of security goal impacts are prevented. Also, we formulated the thrust vector for the proposed framework. The findings indicate that the suggested approach increases trust by 61.36% while reducing costs by 60.16%.
