name: NEA
full_form: Encryption Algorithm for 5G
context: (TVP) is in an acceptable window. Integrity and encryption mechanisms are applied to the message according to the identified protection level, by using the information in the SA (keys, algorithms). a) If the result after applying such mechanisms is NOT successful then the message is discarded. b) If the result after applying such procedures is successful, then SS7-SEG has the cleartext TCAP message NEa originally wanted to send to The cleartext TCAP message can now be forwarded by the receiving SS7-SEG to (Process goes to END) END: A cleartext TCAP user message is available at the receiving SS7-SEG. In the event the received message at NEb requires an answer to NEa (Return Result/Error), an SS7 SEG in PLMN B will, on behalf of NEb perform the process in steps 1 to 4 acting as the Sender and an SS7 SEG in PLMN A will perform the process in steps 5 to 8 acting as the Receiver and forward a successfully received message to NEa.
description: NEA is an entity or endpoint involved in the exchange of TCAP messages and the application of encryption mechanisms for secure communication.
explanation: The classification as Miscellaneous is due to the lack of a clear fit into other predefined categories based on the provided context. The description highlights NEA's role in the message flow and security procedures, but it does not neatly align with standard network functions, protocols, or interfaces.
