Prototype Implementation of Edge Encryption in IoT Architecture

In the IoT system, captured plaintext data is sent to the cloud for storing, computing and further processing. But it is a potential concern to secure sensitive information like personal, financial, business, medical, etc. A certain number of researchers established IoT architecture with distinctive layers where data security is solely dependent on cloud service providers (CSPs) which make potential security threats. In this paper, an edge encryption support in the IoT architecture is implemented where the involvement of CSPs for security purposes becomes nullified. As the data become encrypted before it gets sent to the cloud, it becomes more secure and reliable for both the owner and shared users. Additionally, only the IoT node owner and shared users can access those data which provides better security, privacy, and control of data.
