Lightweight Ring Learning With Errors Cryptographic Scheme for Secure Cloud-IoT Systems

The Internet of Things is giving rise to a hyper-connected world in which people as well as things can communicate with one another. Integration of the Internet of Things technology with Cloud Computing has been recommended as a new paradigm, to overcome the present restrictions of IoT such as low power, volume and performance. However, there are security issues which need to be fixed in the new converged paradigm so as to reduce the risks associated with information protection and management. This work proposes a lightweight Ring Learning With Errors (RLWE) homomorphic encryption communication protocol for user and message management to secure the Cloud-IoT systems. The experiment shows the feasibility of the proposed lightweight RLWE for usage on resource constrained IoT or Edge Computing type of environments for the future smart application ecosystems.
