摘要： A method for authentication of elements of a group, especially for authentication of sensor nodes in a preferably wireless sensor network is disclosed. The group has one specific element—leading element—with which each of the group elements can exchange information and wherein the authentication of the group elements takes place with regard to the leading element. The leading element sends an authentication request to the group elements wherein the authentication request is the same for all the group elements. The group elements each send authentication responses—based on the authentication request—to the leading element, with the authentication responses being different for each group element.

摘要： In a method for distributing keys for encrypted data transmission in a sensor network, nodes store a subset of keys from a set of keys. A sink node triggers the key election procedure and sensor nodes choose from a locally broadcasted keyID list, with one key to be stored on each node. All other initially stored keys are subsequently deleted. The process is repeated until the edge of the network is reached. Such key predistribution is suitable for the encryption of reverse multicast traffic to the sink node which is the predominant traffic pattern in wireless sensor networks.
