A Study On ID-based Authentication Schemes for Telecare Medical Information System
This is an incremental study that identifies vulnerabilities in authentication schemes for medical information systems, which could impact healthcare providers and patients relying on secure remote access.
The study analyzed existing smart card-based authentication schemes for Telecare Medical Information Systems (TMIS), highlighting that inefficient login and password change phases can lead to denial-of-service attacks and increased communication and computation overhead, thereby reducing system performance.
The smart card based authentication schemes are designed and developed to ensure secure and authorized communication between remote user and the server. In recent times, many smart card based authentication schemes for the telecare medical information systems (TMIS) have been presented. In this article, we briefly discuss some of the recently published smart card based authentication schemes for TMIS and try to show why efficient login and password change phases are required. In other word, the study demonstrates how inefficient password change phase leads to denial of server attack and how inefficient login phase increase the communication and computation overhead and decrease the performance of the system.
