Anonymous Cross-domain Authentication Scheme for Medical PKI System
Nowadays,most information systems of hospitals are estab-lished based on Public Key Infrastructure(PKI).Each of them has a certificate authority(CA)act as a trust anchor for all the members it authorized.However,each hospital builds system according to its own understanding and form a lot of isolated domains.In medical application scenario,patients often passively need to change hospitals because of different medical levels and different diseases.For hospital cannot electronically share medical data,which cause lots of waste of resource such as repeated treatment and time consuming.The solution to medical information sharing be-tween hospitals becomes urgent.In this paper,we propose blockchain-based cross-domain authentication scheme for doc-tor users and designed corresponding protocols to support supervision department and user privacy protection.The security analysis and engineering tests demonstrate that the scheme can better meet the requirements of cross-domain authentication and provide better privacy protection services when sharing medical data.
