Abstract
A method of providing authentication at a communication device is provided. A primary authentication is run with a Trusted Non-3GPP Gateway Function TNGF node to obtain a TNGF Key (K). A re-authentication Root Key (rRK) is provided based on the TNGF key. A re-authentication Master Session Key (rMSK1) is derived based on the re-authentication Root Key. A security setup is performed with a Trusted Non-3GPP Access Point TNAP using the re-authentication Master Session Key. Related methods of performing authentication using a Trusted Non-3-GPP Gateway Function are also discussed.
