Abstract
Smart architecture is the concept to manage the facilities via internet utilization in a proper manner. There are various technologies used in smart architecture such as cloud computing, internet of things, green computing, automation and fog computing. Smart medical system (SMS) is one of the application used in architecture, which is based on communication networking along with sensor devices. In SMS, a doctor provides online treatment to patients with the help of cloud-based applications such as mobile device, wireless body area network, etc. Security and privacy are the major concern of cloud-based applications in SMS. To maintain, security and privacy, we aim to design an elliptic curve cryptography (ECC) based secure and efficient authentication framework for cloud-assisted SMS. There are six phases in the proposed protocol such as: patient registration phase, healthcare center upload phase, patient data upload phase, treatment phase, checkup phase and emergency phase. In CSEF, there are four entities like healthecare center, patient, cloud and doctor. In CSEF, mutual authentication establishes between healthcare center and cloud, patient and cloud, doctor and cloud, and patient and healthcare center by the using ECC and hash function. The CSEF is secure against security attacks, and satisfies many security attributes such as man-in-the-middle attack, impersonation attack, data non-repudiation, doctor anonymity, replay attack, known-key security property, message authentication, patient anonymity, data confidentiality, stolen-verifier attack, parallel session attack and session key security. Further, the CSEF is efficient in terms of computation and communication compared to others related frameworks. As a result, CSEF can be utilized in cloud-based SMS.

We aim to proposed a cloudbased secure and efficient mutual authentication framework using elliptic curve cryptography (ECC) for smart medical system
- The mutual authentication is established among patient, cloud server, healthcare center and doctor to build up the security of a architecture and communicating information
Summary
There are billions of devices which are associated with IoT framework for different applications. In 2015, Amin et al proposed key agreement scheme for healthcare system [23], He et al provided robust anonymous authentication framework for TMIS [34], Zhou et al offered a safe and efficient framework for cloud-assisted wireless body area network [48]. In 2020, Chen et al [63] proposed a secure electronic medical record authorization system for smart device application in cloud computing environments, Mo et al [64] proposed an improved anonymous authentication protocol for wearable health monitoring systems and Alzahrani et al [65] proposed a secure and efficient remote patient-monitoring authentication protocol for cloud-IoT. Communication between entities in cloud-based SMS is vulnerable to many attacks, such as replay, man-in-the-middle, impersonation, anonymity, known-key security, data confidentiality, data non-repudiation, message authentication, stolen-verifier attack, privileged-insider attack and parallel session attack. We aim to proposed a cloudbased secure and efficient mutual authentication framework using ECC for smart medical system
