Secure and Light weight Data Sharing Scheme in Cyber Physical Cloud Environment

Abstract

It is still difficult to achieve secure and effective file storage and sharing via authenticated physical devices in a cyber-physical cloud environment because of the variety of devices used to access the services and data, as well as the geographical dispersion of these devices. In this circumstance, a wide variety of cryptographic alternatives are currently available. But the computational and communication overheads are slightly high, and we also need a safe, lightweight, and user-friendly technology. Thus employing a scrambling and unscrambling technique using Sudoku inspired Data Chunking and Scrambling (SiDCS) method. In this approach, the data is scrambled and then unscrambled using Sudoku puzzles. Before being stored in a public cloud, the original data is split up and scrambled. The data will be saved in the cloud independently and securely since each data chunk will only contain a minimal amount of information and because it is scrambled before being stored there. As a result, the cost of communication is reduced, computational overhead is reduced, and a simpler, lightweight model is developed without compromising the security.
