An Efficient Hierarchical Key Management Scheme for Access Medical Database

This paper improved the secure mechanism which existed some shortcomings. In order to accomplish the decentralized environment access control, it also proposed another new mechanism to achieve the requirements on the nonspecific internet. Besides, considering the security on storing and controlling and the use of administrative privileges of the lately popular medical system integration environment and electronic medical records clouds is necessary. With the new mechanism, the problems such as mobile security or acting calculation which derived from Medical System Environment and Electronic Medical Records could be solved. This new research achieves a better circumstance. Medical staff's responsibility can be allocated; the systems can be compatibly integrated; on the other hand, the patients' privacy of personal information can be strictly protected.
