Secure Patient Authentication Scheme in the Healthcare System Using Symmetric Encryption

Abstract

Recently, the incorporation of state-of-the-art technology such as Electronic Healthcare Records (EHRs), networks, and cloud computing has transformed the traditional healthcare system. However, security problems have arisen as a result of the integration of technology. Secure remote user authentication is a core part of the healthcare system to validate the user’s identification via an unsecured communication network. Since then, several remote user authentication schemes have been presented, each with its own set of pros and limitations. As a result, security, malicious attacks, and privacy concerns are considered one of the main challenges related to the healthcare system. In this paper, we propose a safe user authentication scheme for patients in the healthcare system that overcomes these flaws and confirms the security of the proposed work using scyther, a formal security tool. In the healthcare environment, our work provides an effective means to construct an environment capable of setting, registering, storing, searching, analyzing, authentication, and verifying electronic healthcare information in order to protect the information of patients. Furthermore, our suggested scheme uses symmetric encryption based on the crypto-hash function for accessing the anomaly of the patient’s identity and One-Time Password (OTP). Towards the end of the study, the performance analysis results indicate a delicate balance of security and performance that is frequently lacking in previous works.

“…The results show that our proposed scheme required time is less than some related works results and a little higher than others and this is because our scheme provides more security requirements than other schemes.

Towards for Designing Educational System Using Role-Based Access Control

“…In this paper, we propose RBAC, whose fundamental tenet is that roles are made up of operations that correspond to the actions performed by users who have been correctly assigned to these roles as well as to the relationships among users, roles, and operations [8]. We propose a verification scheme to protect the system from some of the most well-known cyberattacks, including phishing, MITM, insider, and reply attacks.…”
