The first apparatus may apply an authentication-encryption function to each NDEF record of the set of NDEF records based on the NDEF record header of each NDEF record, the NDEF record payload of each NDEF record, and a value associated with each NDEF record to obtain a set of authentication-encrypted NDEF record payloads respectively corresponding to the set of NDEF records. Each authentication-encrypted NDEF record payload may include an encrypted NDEF record payload and an authentication tag associated with a corresponding NDEF record. The first apparatus may transmit a protected NDEF message including the set of authentication-encrypted NDEF records to a second device.

The first NFC device may monitor RF activity on a first RAT to determine whether there is at least a greater probability that a second NFC device is within a threshold. The NFC device may be also configured to modify at least an interval between polling modes in a NFC RF discovery loop based on the determination.

Abstract: Aspects disclosed herein relate to providing peer communications between NFC enabled devices using an active communication mode. In one example, a communications device is equipped to detect a remote NFC device field within an operating volume, establish a peer communication link with the remote NFC device using an active communication mode, determine that the peer communication link is to be deselected, and transmit a deselection request message to the remote NFC device indicating to the remote NFC device that it has been deselected while maintaining the peer communication link. In another example, a communications device is equipped to sense an operating volume, as part of an active communication mode collision avoidance procedure, determine that no field is sensed, initiate an unmodulated carrier as part of switching an operating field to an on state, and maintain the unmodulated carrier for a collision avoidance threshold duration of time.

Abstract: Methods, apparatuses, systems, and computer-readable media for reducing Near Field Communication (NFC) Peer Mode connection times are presented. According to one or more aspects, a mode switching interval associated with an NFC device discovery loop may be defined. A first portion of the mode switching interval may be assigned to polling operations. A second portion of the mode switching interval may be assigned to listening operations. The first portion and the second portion of the mode switching interval respectively may occupy less than all of the mode switching interval, and the second portion of the mode switching interval may be shifted in position within the mode switching interval for respective iterations of the NFC device discovery loop.
