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: This disclosure relates to techniques, base stations, and user equipment devices (UEs) for performing base station authentication through access stratum signaling transmissions. The UE may operate in idle mode and may receive an authentication message from a base station through the wireless interface while operating in idle mode. The UE may determine whether a signature comprised within the authentication message is valid, and the UE may continue a connection procedure with the base station based on a determination that the signature is valid. If it is determined that the signature is invalid, the UE may designate the base station as a barred base station and may perform cell re-selection. The authentication message may be one of a radio resource control (RRC) connection setup message, a special RRC message, a media access control (MAC) message, or a random access channel (RACH) message comprising a random access response (RAR) message.

Abstract: Techniques disclosed herein relate to the authentication of a first user in a communication session between the first user using a user device and a second user using a remote computer system. The computer system sends an authentication request in the session, and the user device receives the authentication request in the session via a messaging program. The user device then causes a different program to access an authentication token received from an authentication computer system. The user device sends an indication of the authentication token to the remote computer system which the remote computer system verifies to authenticate the first user within the session.

Abstract: One embodiment provides a system that implements a 1-bit protocol for differential privacy for a set of client devices that transmit information to a server. Implementations may leverage specialized instruction sets or engines built into the hardware or firmware of a client device to improve the efficiency of the protocol. For example, a client device may utilize these cryptographic functions to randomize information sent to the server. In one embodiment, the client device may use cryptographic functions such as hashes including SHA or block ciphers including AES to provide an efficient mechanism for implementing differential privacy.

Abstract: Some embodiments provide a method for providing public keys for encrypting data. The method receives (i) a first request from a first source for a public key associated with a particular user and (ii) a second request from a second source for the public key associated with the particular user. In response to the first request, the method distributes a first public key for the particular user to the first source. In response to the second request, the method distributes a second, different public key for the particular user to the second source. Data encrypted with the first public key and data encrypted with the second public key are decrypted by a device of the particular user with a same private key.

Abstract: A method of identifying invalid participants in a synchronization group. The method generates a device synchronization group identifier (DSGI) for a first device from a device-specific key of the first device. The method joins the first device in the synchronization group by using the DSGI of the first device. Prior to the joining of the first device, the synchronization group stores a set of DSGIs of a set of devices that have joined the synchronization group. The method determines that a particular DSGI stored in the synchronization group is the same as the DSGI of the first device. The method identifies the particular DSGI stored in the synchronization group as a DSGI of an invalid participant of the synchronization group.
