Abstract
A method is for generating, in a UICC, a 5G subscriber concealed identifier, SUCI, for a 5G mobile communication network. The method includes the steps executed in a processing entity comprised in the UICC: (1) generation of a public/private key pair or an ECC public/private key pair; (2) DH or ECDH derivation of an Ephemeral shared key from the generated or ECC public/private key pair; (3) derivation of a symmetric encryption key from the Ephemeral shared key; (4) concealment of at least a part of a subscriber permanent identifier, SUPI, with the generated symmetric key to compute the SUCI. Steps (1, 2) are triggered by a deterministic event at the UICC, and storing the generated or ECC public/private key pair and Ephemeral shared key to a key memory provided in the UICC; and subsequently steps (3, 4) are triggered by receipt of a GET IDENTITY command.
