LSP-eHS: A Lightweight and Secure Protocol for e-Healthcare System

Recent events dedicated to e-healthcare systems demonstrated that a critical mass of users using e-health services and applications are being created and producing a tremendous output, such as improved patient monitoring, faster diagnosis, and better disease management. However, despite the benefits and availability of e-health systems, widespread adoption in real-life medical or health situations still needs to be improved. Therefore, implementing a four-party authentication system can help address concerns about security and privacy and encourage patients to adopt electronic healthcare technologies. This article presents a security protocol for securely authenticating four participants in the e-healthcare system, namely LSP-eHS. The scheme uses a simple cryptographic hash function, concatenation, and xor operations. The security of the proposed protocol can be confirmed through a widely used BAN (Burrows-Abadi-Needham) logic, and the performance analysis of the proposed protocol can be finished by measuring communication and computation costs.
