Latest Patents

Laurent Eschenauer holds a patent for a "Method and apparatus for key management in distributed sensor networks." This patent outlines a comprehensive method of key management that is executed in several phases. The key pre-distribution phase involves distributing a ring of keys to each sensor node before deployment. Each key ring consists of randomly chosen keys from a large pool generated offline. A shared key exists between two key rings with a predetermined probability.

In the shared key discovery phase, which occurs upon deployment, each sensor node identifies its neighbors within wireless communication range that share keys. This process establishes the topology of the sensor array by forming secure communication links between the respective sensor nodes. The path key establishment phase assigns a path key to selected pairs of sensor nodes that do not share a key but are connected by two or more links. Additionally, the key management scheme includes a revocation phase for removing the key ring of any compromised sensor node from the network, as well as a re-keying phase for removing keys that have expired.
