CLOUD BASED SECURE INFRASTRUCTURE FOR IOT DEVICES

Abstract

The proliferation of IoT technology has transformed various businesses but at the same time, it has provided access to a huge number of physical devices deployed in the network. The IoT devices are susceptible to multiple security threats and challenges, device authentication, and verification being one of the foremost. Research work in this dimension has been carried out and multiple solutions have been provided however an end-to-end security solution is required which encompasses the IoT devices, Fog layer, and Cloud computing paradigms. This paper presents a secure and trusted framework for anonymous authentication and data integrity while protecting the system against unauthorized access, impersonation and repudiation attacks in the IoT environment. To achieve our objectives, in this paper IoT devices are integrated with blockchain to create, publish and manage their identities anonymously which will be verifiable without consulting a centralized third party to authenticate the IoT devices. The designed protocol is verified using formal verification tool ‘Scyther’ and it satisfied various security attributes mandatory for authentication and data integrity protocols
