Methods, systems, computer-readable media, and apparatuses for providing anti-rollback protection in a device which has no internal non-volatile memory are presented. One embodiment is a device for providing anti-rollback protection. The device may obtain a firmware version number associated with a first firmware installation for the device, wherein the device is implemented on a substrate that includes no non-volatile memory. The device may obtain a lowest acceptable firmware version number, wherein the lowest acceptable firmware version number is stored in a secure element environment, wherein the secure element environment utilizes memory separated from the substrate. The device may compare the firmware version number and the lowest acceptable firmware version number, wherein if the firmware version number is less than the lowest acceptable firmware version number, then disallow the first firmware installation.

Methods for providing anti-rollback protection of a firmware version in a device which has no internal non-volatile memory

Disclosed are methods, apparatus, systems, computer program products, and other implementations, including a method that includes determining a source from which routing table information is to be obtained based, at least in part, on location data indicating the source, and receiving configuration information from a device host (DH). The method also includes removing DH-based routing table information included in the configuration information in response to the location data indicating that a near-field communication controller (NFCC) is configured to receive the routing table information from one or more secure computing environments or from the DH, and obtaining secure routing table information from at least one of the one or more secure computing environments.

Methods and apparatus for secure updates to persistent data in a near field communication controller

The present application presents example data routing methods and apparatuses for reducing the amount of nonvolatile memory required to store secure element application locations associated with a near-field communications device. For example, the present disclosure presents a method of communication routing in a near-field communication device, which can include receiving, at a near-field communications controller (NFCC), a routing request message (e.g. from a requesting device), wherein the routing request message includes an original application identifier (AID) associated with an application. The example method may also include generating a compressed AID by applying a hash function to the original AID, reading an entry corresponding to the compressed AID in a routing data structure, wherein the entry contains one or more secure element pointers associated with one or more secure elements, and querying at least one of the secure elements to determine whether each contains the application.
