In the last few years, the Internet of Things (IoT) has become important part of our lives and its influence is expected to exponentially increase in the next years. Computer systems and applications are improved day by day and with the advancement in such area it gives birth to new cyber-attacks. Man in the Middle attacks (MITM) are one of those attacks. An attack where an outsider or third party enters in between two online users, where both of the users are unaware of it. Mainly it is knowing as a protocol to an unauthorized user within the system who can access as well as change the information of the system without leaving any trace to the existing users. Cloud, edge and fog computing added more flavors in terms of better throughput and low latency in ease of accessing data. Edge computing refers to a distributed open platform which helps off-loading tasks and processing of cloud at edge of the network. The edge serves as a bridge between the digital and physical worlds making gateways, systems and services smart and efficient. Due to the exponential growth of IoT produced data, its complexity is also expected to increase and raises need for innovation for improved security in Mobile Edge Computing (MEC) environment. This research is conducted to propose a lightweight Blockchain solution using private/ public keys and employing shading for off-loading computation intensive tasks at MEC. Inter-Planetary File System (IPFS) database has been used to offload computational task from edge servers. Proposed technique is implemented using Java Script and Node.JS and simulated through Visual Studio Code and results are compared with other lightweight encryption algorithms proposed for IoT.
