Abstract
A wireless transmit/receive unit (WTRU) may be configured to receive a key identifier. The key identifier may be associated with a second WTRU. Additionally, or alternatively, the key identifier may include a 5G ProSe remote user key (5GPRUK) identifier (ID). The WTRU may be configured as a WTRU-to-network relay for the second WTRU. The key identifier may be received during a key request procedure. The key request procedure may be performed by the WTRU on behalf of the second WTRU. The WTRU may be configured to send the key identifier to a network function. The key identifier may be sent to the network function to initiate a secondary authentication procedure. The WTRU may be configured to receive an authentication response message from the second WTRU. The WTRU may be configured to receive a response from the network function.
