The Research And Design Special PKI Of The Regional Health Information System

With the developing of the network technology, sharing and exchange of the medical information have been offered the feasible platform and technological guarantee. Information sharing is the key content of the network developing. It is a demand for realizing modernized development of the medical system that we should structure the regional health system based on network sharing the medical information as the core.The regional health system is a researching and developing project of our lab. In health system, the privacy of data is the center that pays attention to doubly. Which data can be visited is key problem of medical system. On three layers system structure, Set up the special-public key infrastructure of the regional health system, in order to meet the framework of the whole system Have realized the design of the authentication centre and design of the customer end. And design a kind of management scheme of the key in PKI to convenience the user.Using such technology as RSA, DES, DSA cryptography and Active Directory, LDAP, XML technology, etc. to structure the regional health PKI system. It can realize sharing, inquiry and exchange the patient of case. Let legal user can get case information by any way or by any place conveniently.The special public key infrastructure of the regional health system, it is for guaranteeing the security in the regional health system better, the security service that it offers can not have been combined with the safe demand of the whole system together sewing, keep the characteristic of loose coupling at the same time.
