摘要： The invention relates to a network with a first node (102) comprising first pre-distributed keying material being assigned to the first node before the first node is connected to the network and a second node (104) comprising second pre-distributed keying material being assigned to the second node before the second node is connected to the network. The first node is configured to establish a secure communication (112) to the second node based on the first and second pre-distributed keying materials, without relying on a trust center (108). Pre-distributed keying materials can be replaced in a secure manner with post-deployed keying materials by the network trust center. Nodes can establish further secure communications based on post-deployed keying materials.

摘要： When installing and maintaining a wireless sensor network in a medical or factory environment, distribution of keying material to sensor nodes (18) is performed by a key material box (KMB) (12), such as a smartcard or the like. The KMB (12) has a random seed stored to it during manufacture, and upon activation performs an authentication protocol with a sensor node (18) to be updated or installed. The KMB (12) receives node identification information, which is used in conjunction with the random seed to generate keying material for the node (18). The KMB (12) then encrypts the keying material for transmission to the node (18), and transmits over a wired or wireless communication link in a secure manner. The node (18) sends an acknowledgement message back the KMB (12), which then updates the nodes status in look-up tables stored in the KMB (12).

摘要： A medical ad hoc wireless network (10) is deployed in a healthcare medical facility surrounding individual patients and including wireless nodes (A, B, . . . , Z). Before deployment, each node (A, B, . . . , Z) is pre-initialized with a public key certificate (22) and offers a trust and symmetric key distribution service (32). In joining the ad hoc network (10), a node (B) authenticates and registers to one randomly self-chosen node (A) by using certified public keys (20). Such node (A) becomes Trusted Portal (TPA) of the node (B). The node (B) dynamically registers to a new self-chosen TP node when its old TP node leaves the ad hoc network (10). The network (10) supports symmetric key authentication between nodes registered to the same TP node. Additionally, it supports symmetric key authentication between nodes registered to different TP nodes.
