Enhanced ubiquitous system architecture for securing healthcare IoT using efficient authentication and encryption

In the light of the ongoing development of IoT (Internet of Things) technology and the rise of Futuristic Smart Vertical Networks, its utilisation in diverse sectors is growing more widespread, resulting in heightened productivity and improved quality of life. The widespread implementation of the Internet of Things (IoT) in the medical field has multiple benefits. It enhances patient access to medical services and enables healthcare professionals to obtain timely and accurate information about patients' physical conditions. Consequently, this facilitates the development of more efficient and targeted treatment approaches. However, despite the enjoyment consumers experience from the conveniences offered by the Internet of Things (IoT) in the healthcare sector, it is crucial to priorities protecting patients' communication security and personal privacy. This study introduces a novel enhanced ubiquitous system architecture protocol to enhance user access to networks by implementing an efficient method for anonymous authentication and key exchange. The system is based on the principles of homomorphism encryption. This protocol aims to enable mutual authentication between medical devices and distant medical servers by utilising a passphrase with low entropy. This process ultimately results in generating a session key with high entropy. The scheme's security is verified inside the standard model, and simulated experimental outcomes highlight its enhanced efficiency compared to similar current alternatives.
