An Integrated Two-Stage Medical Pre-Checkup and Subsequent Validation Key Agreement Authentication Mechanism

Abstract

In the global village era, several competitions require pre-checkups for the participants who are qualified to participate that must be passed before the competition, so the accuracy of the checkup data must be confirmed and must not be leaked or tampered with. This is a new challenge to the accuracy of medical checkups data in the information and communication era. How to protect the rights of participants and the non-repudiation of participants are the main issues of this study. We have designed a two-phase user identity embedding and authentication scheme for pre-checkups and subsequent validations. A participant’s private key is added to the physical examination data, and the identity of the examinations data is confirmed by the contestant before the competitions. Our work integrates lightweight Exclusive-OR (XOR) operations, fuzzy extractor biometric personal passwords, and a fixed-length hash operation accords with post-quantum operations to solve the problem of two-stage medical pre-checkup and subsequent validation key agreement authentication. The random oracle authentication mechanism proves the security of the protocols, and the security analysis proves that the protocols can resist the vulnerability attacks.
