Abstract
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.
