Abstract:
A method performed by an authentication server in a home network of a UE for obtaining a subscription permanent identifier, SUPI. The method comprises: receiving a SUCI which comprises an encrypted part in which at least a part of the SUPI is encrypted, and a clear-text part which comprises a home network identifier and an encryption scheme identifier that identifies an encryption scheme used by the UE to encrypt the SUPI in the SUCI; determining a de-concealing server to use to decrypt the encrypted part of the SUCI; sending the SUCI to the de-concealing server; and receiving the SUPI in response. Methods performed by a UE and a de-concealing server are also disclosed. Furthermore, UEs, de-concealing servers, authentication servers, computer program and a memory circuitry are also disclosed.

Claim (Index 11):
A method, performed by a de-concealing server, for providing a subscription permanent identifier (SUPI) to an authentication server, the method comprising:\n receiving, from the authentication server, a subscription concealed identifier (SUCI) which comprises an encrypted part in which at least a part of the SUPI is encrypted, and a clear-text part which comprises a home network identifier and an encryption scheme identifier that identifies an encryption scheme used by a UE to encrypt the SUPI in the SUCI and which is supported by the de-concealing server; decrypting the encrypted part of the SUCI, using the encryption scheme indicated by the encryption scheme identifier to obtain the SUPI; and sending the SUPI to the authentication server.
