Proposed IoT framework using third party with enhanced security

Internet of Things (IoT) is the future of next era of the Internet which connects various physical objects by communicating with each other without the aid of human interactions. Applications of IoT become important in day to day lifestyle such as healthcare, smart grid, smart home, smart parking. Various IoT sensors such as temperature sensors, fault sensors track monitoring sensors are used to make an intelligent railway system which monitoring the railway stations. IoT application is useful to human yet if the IoT system shield the client data from a hacker, attacks, and vulnerabilities. Security plays an important role in network to prevent the unauthorized access, misuses of data, monitoring and data, modification etc. In conventional network security, intruder may destroy modification, monitor the information and allow the unauthorized person to access the system. Similarly, IoT is endured from various security attacks. Although we have numerous cryptographic algorithms, however these are not suitable for constrained devices because of their large key size like RSA. Our proposed security IoT architecture generates a secret key and its administration by the notarization mechanism for securing the data.
