Abstract: An initiator device and a target device may be configured to communicate with each other based on an anonymous key agreement procedure and an associated key agreement procedure. The anonymous key agreement procedure is performed for an initial communication session between the devices based on bonding identifiers (BIs) received in an attribute request/response. The BIs may be maintained by the devices to forego the anonymous key agreement procedure for subsequent communication sessions, where the devices may instead communicate based on an associated key agreement procedure. In cases where BIs are changed or lost by one of the devices, the associated key agreement procedure may not be performed and the anonymous key agreement procedure may be again attempted by the device. The other device is configured to determine that the anonymous key agreement procedure is being attempted and complete the anonymous key agreement procedure in an anonymous mode.

Abstract: A method for determining a distance upper bound by a verifier device is described. The method includes measuring a first round-trip time to receive a first response from a target device corresponding to a first message sent to the target device. The method also includes measuring a second round-trip time to receive a second response from the target device corresponding to a second message sent to the target device, the second response being delayed by a processing time multiplier. The method further includes determining a transit time measurement based on the first round-trip time, the second round-trip time and the processing time multiplier. The method additionally includes determining the distance upper bound based on the transit time measurement.

Abstract: Examples herein disclose apparatus and methods for NFC authentication using NDEF message exchange. In one example, a mapping from the NFC Authentication process to suitable NDEF records and messages occurs during the bonding and authentication phases. This may include new NDEF record types plus a mapping of the relevant steps in the NFC authentication process where data is exchanged to the NDEF messages that are to be used in each step and new mechanisms by which errors can be indicated and detected by the devices.

Abstract: Systems and methods for protecting privacy and security of information transmitted from a card device to a Point of Sale (POS) device during a financial transaction. The POS device may obtain payment information comprising private information from the card device and implement one or more filtering rules to prevent the private information from being accessed by unauthorized applications on the POS device. For a Near Field Communication (NFC) based transfer of payment information from the card device to the POS device, the one or more filtering rules may be implemented in an NFC Controller Interface (NCI) Filter Application having one or more Privacy Management Gates to prevent the private information from being transferred out of the NFC Controller to an unauthorized reader.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In certain implementations, the apparatus may perform a first key agreement procedure to determine a first shared secret for communicating with a second device. In one aspect, the first shared secret may be associated with first BI of the first device and a second BI of the second device. The apparatus may maintain a first correlation between the first shared secret and the second BI. The apparatus may perform a key agreement recovery procedure when it is determined that the second device does not maintain a second correlation between the first shared secret and the first BI.

Abstract: Systems and methods for protecting privacy and security of information transmitted from a Secure Element, such as UICC/eUICC embedded in a processing system, include privacy management units for determining if information transmitted from the Security Element to an external entity comprises data to be masked. If the information comprises data to be masked, gates at endpoints of interfaces between the Secure Element and the external entity are configured with one or more masking rules. The privacy management units may apply the one or more masking rules to selectively mask or omit data before the information is transmitted to the external entity for logging.

Abstract: Methods, apparatus, and computer program products for protecting information stored on a computing device are described. An example of a method includes generating a first encryption key based on a previously stored factory reset value, encrypting, by a processor, at least a portion of information associated with an application using the first encryption key, storing the encrypted at least the portion of the information associated with the application in a memory of the computing device, obtaining, by the processor, a request for a factory reset of the computing device, in response to the request for the factory reset of the computing device, replacing, by the processor, the previously stored factory reset value with a new factory reset value, and disabling decryption of the stored encrypted at least the portion of the information associated with the application by generating a second encryption key based on the new factory reset value.

Abstract: The disclosure relates to enhancing performance at a device that implements a stand-alone global navigation satellite system (GNSS) receiver. In particular, a GNSS-enabled mobile device may obtain positioning data from one or more non-satellite sources and determine satellite signal quality in a surrounding environment. As such, in response to determining that the environment surrounding the GNSS-enabled mobile device is a weak satellite signal environment, the GNSS-enabled mobile device may trigger a process to provide the positioning data obtained from the one or more non-satellite sources to the device that implements the stand-alone GNSS receiver such that performance at the device that implements the stand-alone GNSS receiver may be enhanced in poor satellite signal environments.

For example, with a near field communication (NFC) device, a NFCC may be configured to obtain a first radio frequency (RF) technology and mode value, a second RF technology and mode value, and one or more RF specific parameters associated with a NFC device during an activation phase of a communication link using a first NFC RF technology. The one or more RF specific parameters may be based on the first RF technology and mode value. Further, the NFCC may be configured to configure communications to be supported by a second NFC RF technology for use during a data exchange phase of the communication link. The second NFC RF technology may be based on the second RF technology and mode value.
