Zusammenfassung:	The disclosure relates to methods of validating a SUCI implemented by a network node in a mobile network. The network node receives a message including the SUCI. Responsive to receipt of the message, the network node obtains a first set of encryption parameters used to generate the SUCI. The network node uses the first set of encryption parameters to de-conceal the SUCI to obtain subscription information associated with a subscription. Subsequently, the network node obtains a second set of encryption parameters associated with the subscription using the subscription information and validates the SUCI based on the second set of encryption parameters. As one example, the network node validates the SUCI by comparing the first set of encryption parameters to the second set of encryption parameters and determining if there is a match.
