Abstract: An electronic device includes a sequence generator module that generates a sequence in a predetermined order based on a traffic class of data to be sent. The sequence is written into a portion of a sequence header of an outgoing data packet that corresponds to the traffic class. A traffic class identifier is also written into a header of the packet that indicates the traffic class of the data. The electronic device sends the packet to another electronic device over one of multiple channels of multiple priorities. The other electronic device determines the traffic class of the data based on the traffic class identifier, extracts the sequence from the portion of the sequence header that corresponds to the traffic class, and compares the sequence to a previously extracted sequence of a previously received packet of the same traffic class to determine whether a replay attack has occurred.

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.
