full_form:                  ProSe MIKEY Key
context: When a MIKEY message arrives at the ME, the processing process as follows: - The UE shall extract PMK @ FQDN of the ProSe Key Management Function for the IDr payload to establish which PMK was used to protect the MIKEY message. - The Timestamp Payload is checked and compared against the stored Counter for the PMK, and the message is rejected if that counter is not larger then the current Counter. - The integrity of the message is checked. If this fails, the message is discarded, otherwise the processing continues as follows. - The counter associated with the PMK shall be set to the values conveyed in the Timestamp payload. - If the PMK used to protect the message is the not the last successfully used one, then it becomes the last successfully used one and any other PMK related to this ProSe Key Management Function is deleted. - The UE shall extract the Group ID and PGK ID from the received IDi Payload. If PGK ID is all zeros, then the UE shall stop processing the message and send a Key
description: The ProSe MIKEY Key (PMK) is a cryptographic key used to protect MIKEY messages within the context of ProSe (Proximity-based Services) communication. It ensures confidentiality and integrity of MIKEY messages by encrypting and authenticating them.
explanation: The description focuses on the PMK's role in securing MIKEY messages through encryption and authentication, placing it firmly within the realm of key management practices used in telecommunications.
