  • Protection of the UE identity during 802.1x carrier hotspot and wi-fi calling authentication
    Patent number: 11553561
    Abstract: This disclosure relates to techniques for performing Wi-Fi authentication in a wireless communication system. Public key cryptography may be used to enhance the confidentiality of the user's permanent identity in transit. In some embodiments, a RSA-OAEP(SHA-256) encryption scheme may be used to protect the permanent identity when the EAP client needs to send the user's permanent identity to the server in the absence of pseudonym or fast re-authentication identity. In some embodiments, a server certificate is used to authenticate a iWLAN tunnel to protect an IMSI during setup of a Wi-Fi call. Using the methods described herein on both or either of the EAP client and server side may offer improved privacy protection.
    Type: Grant
