Proxy re-encryption approach to secure data sharing in the internet of things based on blockchain
International Research Journal of Modernization in Engineering Technology and Science · 2023
Data sharing has developed as one of the most important aspects for internet of things in cloud computing applications.Even though progress of technology is visually attractive but data security becoming a more problem because of its usage of data in inappropriate that leads a result in a variation of bad effects.To overcome this issue We delivered a proxy re-encryption method in this paper that exchange a data in cloud in a safer way.Identity based encryption allows owners to store their threatened information to the cloud, while proxy reset encryption structure allows approved users to access the data.Due to the limited resources of Internet of Things devices availability, an edge device serves as an intermediary in order to handle demanding calculations.the foundation of our system concept is blockchain, a ground-breaking technology that permits decentralized data sharing.It accomplishes very fine guideline of access to data and reduces inadequacies in centralized systems.italso ensures the security, confidentiality and integrity of data.
