Abstract
Cloud computing plays a significant role in digital workplaces and has become an integral part of everyday life. However, the security issues associated with cloud computing remain a major concern that hinders the wider adoption of this technology. In a cyber-physical cloud environment, achieving secure and efficient file storage remains a tough goal. This is particularly the case owing to the wide variety of devices that are being utilised to access the various services and data. Thus, the employment of a secure data sharing protocol is one of the essential techniques to better protect the shared data. A formal agreement between entities or organisations in exchanging personal or business data is called a data sharing protocol. A secure data sharing protocol ensures that data is encrypted and secured when being transferred. There are many different encryption algorithms and protocols in use to devise various secure and efficient data sharing protocols. This paper first reviews the state of the art of some existing data sharing protocols and subsequently implements a secure and efficient data sharing protocol as an application in a cyber-physical cloud environment. The performance analysis conducted on the developed secure data sharing protocol application shows positive results.
