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.

International Classification:

H04L 29/06
H04L 12/24
H04W 12/06

Abstract:

A wireless device determines a location, identifies a mobile network operator (MNO), and/or experiences a network event. In some instances, the wireless device recognizes a base station as being operated by the MNO. Based on the location, the MNO and/or the network event, the wireless device determines a security action. The security action can include one or more of: (i) ignoring a network command associated with the network event, (ii) providing an alert notification via a user interface of the wireless device alerting a user of a security risk associated with the location, MNO, and/or network event, or (iii) ignoring communication from the base station temporarily or for an indefinite period of time. In some instances, the security action includes proceeding with normal communication with the base station at the location using network services of the MNO.
