A Secure Data Sharing Using Identity-Based Encryption Scheme for e-Healthcare System

Data sharing information regarding health status in the e-healthcare systems becomes one of private and very sensitive information that should be kept from exposure by illegal activities. However, since the information are exchanged across public networks (i.e., Internet and wireless networks), the information become vulnerable. Due to the participating users in the network can not be trusted, a secure data sharing process in the e-healthcare system would be mandatory. In this paper, we propose a secure data sharing in the e-healthcare system using Identity-Based Encryption (IBE) with signature to provide: (1) data sharing can be accessed by only authorized users based on unique public identity (ID) and kept its integrity from alteration during transmission simultaneously, and (2) data sharing are encrypted and authenticated such that the data can only be exchanged by authorized users. Meanwhile, experimental results are able to show the practicality of proposed system.
