System and methods for efficient authentication of medical wireless ad hoc network nodes

The medical service group of wireless network (10) is being the individual patient is preventive solar generating device, comprising a wireless nodes (A, B,…; Z). Front using; each node (A, B,…; Z) is respectively is key (22) pre-initialization, and providing trust and symmetrical key distributing service (32). The linkage hoc network (10) node (B) by using the appraised public key (20) authentication and registers random optional node (A). Such node (A) are node (B) trust inlet (TPA). The node (B) on the cutting TP node of the hoc network (10) tendency to as a new optional TP node. The network (10) and is registered the same TP node the symmetrical authentication key between nodes. In addition, comprising support is registered different TP node the symmetrical authentication key between nodes.
