Network relay security

An apparatus for wireless communication comprising a processor, configured to implement a method, the processor configured to:

• receive, by a first network device from a second network device, a first request message that includes an identifier associated with a first communication device;
• transmit, by the first network device to a third network device, a second request message that includes the identifier;
• and
• receive, by the first network device and in response to the second request message, a response message from the third network device, wherein the response message indicates whether the third network device identifies a relay key using the identifier.

A non-transitory computer readable program storage medium having code stored thereon, the code, when executed by a processor, causing the processor to implement a method, comprising:

• receiving, by a first network device from a second network device, a first request message that includes an identifier associated with a first communication device;
• transmitting, by the first network device to a third network device, a second request message that includes the identifier;
• and
• receiving, by the first network device and in response to the second request message, a response message from the third network device, wherein the response message indicates whether the third network device identifies a relay key using the identifier.
