Personal security administrator for ubiquitous patient monitoring

摘要

A comprehensive patient health care system, comprising: - one or more wireless medical sensors adapted to fit a patient's body and communicating with each other forming a network of body sensors within a wireless medical sensor network that includes one or more more networks of body sensors; - means for creating secure λ keys incorporated in each of said wireless medical sensors to enable secure communications between said wireless medical sensors, and - a personal security administrator within the body sensor network and in communication with said one or more wireless medical sensors within said network of body sensors, with said personal security administrator providing secure communications with the final services and providing security relationships within said network of body sensors by means of creating secure λ keys in which said means of Creation of secure λ keys are such that a coalition of no more than λ compromised wireless medical sensors hides a peer key between two wireless non-compromised medical sensors and provides protection against node compromise until λ + 1 wireless medical sensors have compromised, - or A health care card connected to the personal security administrator to form an extended personal security administrator (PSMx), in which the health care card (HCC) includes identification information and security information for secure communication with the health services. Final health care, in which the personal security administrator includes a certificate issued by a local trust center, and in which the system is adapted to execute a security protocol for the audit and / or access control and / or privacy protection, and / or mutual authentication of the personal security administrator with the health care card.
