A Provable Secure and Lightweight Smart Healthcare Cyber-Physical System With Public Verifiability

Abstract

The recent spades of cyber-attacks have compromised patients’ data security and privacy in healthcare cyber-physical systems (CPS) in the era of health 4.0 that integrates the Bio-Medical sensors, Internet of Things (IoT), and cloud technologies. The current research problem with a secure healthcare system for resource-constrained environment is the cost at which a secure healthcare system is achieved. Most existing systems either preserve security and privacy but could not be suitable for a limited resource environment or achieve efficiency but are later found insecure. To solve this issue, this article oversees the equilibrium between the security and efficiency for IoT-enabled secure healthcare platforms. We cryptanalysis Kumar and Chand's system and find their system is insecure due to which the system loses mutual authentication. In this article, we proposed a secure and lightweight smart healthcare CPS system. While preserving the privacy of the system, integrity of patient data on the cloud, and public verifiability of data in the least communication and computation. Additionally, we prove that the proposed solution is secure against indistinguishability under chosen-ciphertext attack and forgeability under chosen message attack.
