【Abstract】In recent years, the concept of the Internet of Things (IoT) is making a 'Thing' in real-world life to be smart by designing the devices to be pervasive, mobile and wearable. The IoT applications may be supported by big data or cloud computing for data analysis. The data analytics has to be performed remotely on the data received from the IoT device. The user has to send highly sensitive personal data to centralized devices for analysis which may lead to serious risks for privacy and security. This can be addressed by IoT systems maintained as peer-to-peer (P2P) systems incorporated with Blockchain technology. Mutual authentication has to be performed to improve the security and trust of IoT applications on a peer to peer basis. This paper addresses two challenges: (i) Mutual authentication is a decentralized P2P IoT environment addressing the tradeoff between privacy and security using Zero-Knowledge Protocol (ZKP) Protocol. ii) The data storage to be secure and for handing it in transparent P2P mode, the Blockchain technology is used for IoT healthcare system. This ZKP protocol has been proved to satisfy the properties of Zero-Knowledge proof systems. The algorithm has been proved to be optimized with respect to space which is one of the limitations of sensor nodes in IoT devices.
