    Abstract: Systems, methods, and computer-readable media for preserving trust data during operating system updates of a secure element of an electronic device are provide. An update package is received to update an existing secure element operating system to a new secure element operating system by exporting trust data from the existing secure element operating system, after the exporting, uninstalling the existing secure element operating system, migrating the exported trust data using a migration operating system when a data format version of the existing secure element operating system is different than a data format version of the new secure element operating system, installing the new secure element operating system, and importing the migrated trust data into the installed new secure element operating system.

    Abstract: A jitter buffer in a Voice over LTE receiver may be influenced by radio level feedback (RLF) from both local and remote endpoints to preemptively adjust the jitter buffer delay in anticipation of predicted future losses that have a high probability of occurring. The radio events of the RLF and the scenarios that trigger the preemptive adjustments may be identified, and their use may be expressed in terms of mathematical formulas. In prior art designs, the instantaneous jitter is derived from a weighted history of the media stream, and consequently only packets that have already arrived are used to compute the instantaneous jitter to adjust the length of the buffer. By providing and using RLF from both local and remote endpoints, the anticipated delay—for packets that have not yet arrived—may be used to preemptively adjust the buffer, thereby minimizing packet loss without introducing unnecessary delay.

    Abstract translation: 在LTE语音接收机中的抖动缓冲器可能受来自本地和远端端点的无线电电平反馈（RLF）的影响，以预先考虑具有高概率发生的预测未来损耗的抖动缓冲器延迟。 可以识别RLF的无线电事件和触发抢先调整的场景，并且可以用数学公式来表示它们的使用。 在现有技术的设计中，瞬时抖动是从媒体流的加权历史导出的，因此只有已经到达的分组被用于计算瞬时抖动以调整缓冲器的长度。 通过从本地端点和远端端点提供和使用RLF，对于尚未到达的数据包，预期的延迟可能被用于抢先调整缓冲区，从而最大限度地减少数据包丢失而不引入不必要的延迟。

    Abstract: During operation, an electronic device may provide, to a second electronic device, an invitation to share a digital car key associated with a user of the electronic device and a vehicle, where the invitation includes information for creating another instance of the digital car key on the second electronic device. Then, the electronic device may receive, from the second electronic device, a message accepting the invitation, where the message includes a certificate associated with the other instance of the digital car key on the second electronic device. Moreover, the electronic device may provide, to the second electronic device, an approved version of the certificate with a digital signature of the user. Next, the electronic device may provide, to the computer, an instruction to share the digital car key with a set of electronic devices, which is associated with a second user of the second electronic device.

    Abstract: The techniques described herein provide for authentication of a reader device over a wireless protocol (e.g., NFC or Bluetooth, BLE). The mobile device can receive and store the static public key of the reader device and one or more credentials, each credential specifying access to an electronic lock. The mobile device can receive an ephemeral reader public key, a reader identifier, and a transaction identifier. The mobile device can generate session key using the ephemeral mobile private key and the ephemeral reader public key and send the ephemeral mobile public key to the reader device. The reader device can receive the ephemeral mobile public key and sign and transmit a signature message to the mobile device. The mobile device can validate a reader signature and generate an encrypted credential that the reader can use to access an electronic lock. The reader device can authenticate the mobile device for mutual authentication.
