Abstract:
Techniques are disclosed relating to authenticate a user with a mobile device. In one embodiment, a computing device includes a short-range radio and a secure element. The computing device reads, via the short-range radio, a portion of credential information stored in a circuit embedded in an identification document issued by an authority to a user for establishing an identity of the user. The computing device issues, to the authority, a request to store the credential information, the request specifying the portion of the credential information. In response to an approval of the request, the computing device stores the credential information in the secure element, the credential information being usable to establish the identity of the user. In some embodiments, the identification document is a passport that includes a radio-frequency identification (RFID) circuit storing the credential information, and the request specifies a passport number read from the RFID circuit.
Abstract:
Techniques are disclosed relating to sharing access to electronically-secured property. In some embodiments, a first computing device having a first secure element receives, from a second computing device associated with an owner of the electronically-secured property, an indication that the second computing device has transmitted a token to server computing system, the token permitting a user of the first computing device access to the electronically-secured property. Based on the received indication, the first computing device sends a request for the transmitted token to the server computing system and, in response to receiving the requested token, securely stores the received token in the first secure element of the first computing device. The first computing device subsequently transmits the stored token from the first secure element of the first device to the electronically-secured property to obtain access to the electronically-secured property based on the token.

Abstract:
Techniques are disclosed relating to secure data storage. In various embodiments, a mobile device includes a wireless interface, a secure element, and a secure circuit. The secure element is configured to store confidential information associated with a plurality of users and to receive a request to communicate the confidential information associated with a particular one of the plurality of users. The secure element is further configured to communicate, via the wireless interface, the confidential information associated with the particular user in response to an authentication of the particular user. The secure circuit is configured to perform the authentication of the particular user. In some embodiments, the mobile device also includes a biosensor configured to collect biometric information from a user of the mobile device. In such an embodiment, the secure circuit is configured to store biometric information collected from the plurality of users by the biosensor.
Abstract:
A device facilitating countersigning updates for multi-chip devices includes at least one processor configured to receive, from a collocated chip, a data item and a software update, the data item being signed using a private key corresponding to a primary entity associated with the collocated chip and the data item comprising an authentication code generated using a symmetric key corresponding to a secondary entity associated with the software update. At least one processor is further configured to verify the data item using a public key associated with the primary entity. At least one processor is further configured to verify the software update based at least in part on the authentication code and using the symmetric key corresponding to the primary entity. At least one processor is further configured to install the software update when both the data item and the software update are verified, otherwise discard the software update.
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. Previously, the instantaneous jitter was derived from a weighted history of the media stream, and consequently only packets that had already been received were 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:
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.
