Patent attributes
The present system having a secure wireless infrastructure with a key server acting as a key distribution center. The key server may be the core of the network, securely admitting new nodes or devices, deploying and updating keys and authorizing secure communications sessions. The system may also share secure keying information with a new device not already a member of a secure wireless network. The keying information may be used for authentication or encryption or both, and may be provided to the new device in a manner or mode which is not susceptible to exposure outside of the secure network. The keying information shared with the new device may be regarded as a birth key. Then the new device may send a birth key encrypted request to join the secure network via an exposed communication mode. The key server may respond with a birth key encrypted key encryption key.
