With the growing demand for smart devices such as smartphones along with various internet services, there is no doubt that communication has been made extremely easy for everyone. IoT is one of the emerging technology that can contribute to a smart city. It is seen that many IoT-based systems are currently used in various sectors from healthcare to parking systems and is proved to be efficient. But IoT suffers from security issues and is vulnerable to attacks. Blockchain on the other hand is a technology that is secured by design. It uses cryptography techniques to secure the data and is meant to be a trusted technology in a trust-less environment. In this paper, we discuss the existing systems that integrate these two technologies and mention the challenges faced when such systems are deployed in a working environment. |
