    Abstract: Techniques are disclosed relating to electronic security, e.g., for authenticating a mobile electronic device to allow access to system functionality (e.g., physical access to the system, starting an engine/motor, etc.). In some embodiments, a system and mobile device exchange public keys of public key pairs during a pairing process. In some embodiments, an asymmetric transaction process includes generating a shared secret using a key derivation function over a key established using a secure key exchange (e.g., elliptic curve Diffie-Hellman), and verifying a signature of the system before transmitting any information identifying the mobile device. In various embodiments, disclosed techniques may increase transaction security and privacy of identifying information.

    Abstract: In order to simplify and reduce the cost of an electronic device, the size of a first non-volatile memory associated with an integrated circuit is significantly reduced. Instead of using the first non-volatile memory, a second non-volatile memory associated with a processor in the electronic device is used to store an embedded operating system of the integrated circuit, as well as associated data and a configuration of the integrated circuit. To reduce the security risks associated with using this remote second non-volatile memory, the first non-volatile memory may store authorization information and anti-replay information. During a secure boot of the integrated circuit, the authorization information is used to verify that the embedded operating system, the data and the configuration are authorized. In addition, the anti-replay information is used to determine that the embedded operating system, the data and the configuration are different than previously received versions of these items.

    Abstract: This disclosure relates to adjusting a jitter buffer at a wireless device based on inter-arrival-jitter (IAJ). In one embodiment, an IAJ value may be calculated for each of multiple received packets. An IAJ distribution may be generated for the received packets. A target packet loss rate may be determined. A quality of service value for IAJ distributions corresponding to the target packet loss rate may be determined. A de-jitter delay value may be calculated based on the IAJ distribution and the quality of service value for IAJ distributions. The de-jitter delay value may be used to adjust the jitter buffer at the wireless device.

    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.
