SECURE NFC DATA AUTHENTICATION
First Claim
1. A mobile device, comprising:
- a wireless transceiver configured to enable wireless data communication via a network;
a host processor configured to control operations of the mobile device;
a security element (SE) configured to allow at least some near field communication;
a near field communication (NFC) system comprising an NFC transceiver and an NFC controller implementing a contactless front end, wherein the contactless front end is configured to;
(i) route a near field communication related to a payment transaction between the NFC system and the SE without going to or from the host processor; and
(ii) route a near field communication not related to a payment transaction, but requiring a security function, between the NFC system and the SE without going to or from the host processor; and
(iii) route a near field communication not related to a payment transaction, and not requiring a security function, between the NFC system and host processor without going to or from the SE.

Abstract
A mobile device includes a wireless transceiver, a host processor, a secure element (SE), and a near field communication (NFC) system having an NFC transceiver and an NFC controller implementing a contactless front end. The contactless front end routes a near field communication related to a payment transaction between the NFC system and the SE without going to or from the host processor. The contactless front end routes a near field communication not related to a payment transaction, but requiring a security function, between the NFC system and the SE without going to or from the host processor. The contactless front end routes a near field communication not related to a payment transaction, and not requiring a security function, between the NFC system and host processor without going to or from the SE.

14. A method comprising the steps of:
-
receiving a data message from a near field communication (NFC) enabled device by a mobile device when within NFC range; determining a mode of operation, wherein the mode of operation is one of; (i) card emulation; (ii) peer-to-peer (P2P);
or(iii) read and/or write; and determining whether a security function is required for the data message; and routing the data message to a security element (SE) of the mobile device without going to the host processor of the mobile device, when not related to card emulation but requiring a security function. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
