Blockchain Solution for Securing Fog-Computing Communications in IoT Applications

IoT is currently experiencing a high rate of global expansion and adoption, which raises many security issues. Identifying viable and applicable solutions to a large and diverse number of devices that need to communicate securely is an issue that needs to be addressed. The protocols, currently used to secure communications, have not been designed for devices with limited resources or for direct communication between network nodes. The paper proposes a secure handshake protocol for use on a distributed blockchain technology and fog-computing architecture for the IoT environment. This solution uses emerging technologies to ensure the security of communications in IoT environments at lower complexity, lower power consumption and lower costs compared to existing solutions on the market.
