A Lightweight Proxy Re-Encryption Approach with Certificate-Based and Incremental Cryptography for Fog-Enabled E-Healthcare

Abstract

Cloud computing aims to provide reliable, customized, and quality of service (QoS) guaranteed dynamic computing environments for end-users. However, there are applications such as e-health and emergency response monitoring that require quick response and low latency. Delays caused by transferring data over the cloud can seriously affect the performance and reliability of real-time applications. Before outsourcing e-health care data to the cloud, the user needs to perform encryption on these sensitive data to ensure its confidentiality. Conventionally, any modification to the user data requires encrypting the entire data and calculating the hash of the data from scratch. This data modification mechanism increases communication and computation costs over the cloud. The distributed environment of fog computing is used to overcome the limitations of cloud computing. This paper proposed a certificate-based incremental proxy re-encryption scheme (CB-PReS) for e-health data sharing in fog computing. The proposed scheme improves the file modification operations, i.e., updation, deletion, and insertion. The proposed scheme is tested on the iFogSim simulator. The iFogSim simulator facilitates the development of models for fog and IoT environments, and it also measures the impact of resource management techniques regarding network congestion and latency. Experiments depict that the proposed scheme is better than the existing schemes based on expensive bilinear pairing and elliptic curve techniques. The proposed scheme shows significant improvement in key generation and file modification time.

“…Some of the researchers also use the concept of paring free identity-based signature schemes [ 90 – 93 ]. A lightweight proxy re-encryption scheme with certificate-based and incremental cryptography for fog-enabled e-healthcare is proposed in [ 94 ].…”

Concept of Joint Functioning of Access Control Systems

“…One of the ways in which reliability of such systems may be ensured is to guarantee the security of information flows. Information security can be described using such properties as: confidentiality, integrity, and availability [1], [2]. Compliance with these properties is ensured in ITS solutions, in particular, by the access control system allowing users to access or prohibiting them from accessing a given organization's resources [3].…”
