A method for operating a voice trigger is provided. In some implementations, the method is performed at an electronic device including one or more processors and memory storing instructions for execution by the one or more processors. The method includes receiving a sound input. The sound input may correspond to a spoken word or phrase, or a portion thereof. The method includes determining whether at least a portion of the sound input corresponds to a predetermined type of sound, such as a human voice. The method includes, upon a determination that at least a portion of the sound input corresponds to the predetermined type, determining whether the sound input includes predetermined content, such as a predetermined trigger word or phrase. The method also includes, upon a determination that the sound input includes the predetermined content, initiating a speech-based service, such as a voice-based digital assistant.

Voice trigger for a digital assistant

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.

Enhanced security for access stratum transmission

Apparatuses, systems, and methods for generating and utilizing improved initialization vectors (IVs) when performing encryption and authentication in wireless communications. In some scenarios, a wireless communication device may generate one or more pseudorandom multi-bit values, e.g., using a respective plurality of key derivation functions (KDFs). A first portion of each value may be used as a respective key for encryption or authentication of traffic on the user plane or the control plane. A second portion of each value may be used as a nonce value in a respective IV for use with a respective key for encryption or authentication of traffic on the user plane or the control plane. In some scenarios, the nonce values may instead be generated as part of an additional pseudorandom value (e.g., by executing an additional KDF), from which all of the IVs may be drawn.

Initialization vector generation when performing encryption and authentication in wireless communications

A wireless device determines a location, identifies a mobile network operator (MNO), and/or experiences a network event. In some instances, the wireless device recognizes a base station as being operated by the MNO. Based on the location, the MNO and/or the network event, the wireless device determines a security action. The security action can include one or more of: (i) ignoring a network command associated with the network event, (ii) providing an alert notification via a user interface of the wireless device alerting a user of a security risk associated with the location, MNO, and/or network event, or (iii) ignoring communication from the base station temporarily or for an indefinite period of time. In some instances, the security action includes proceeding with normal communication with the base station at the location using network services of the MNO.

Cellular security framework

A memory device may comprise circuitry to adjust between latency and throughput in transferring information through a memory port, wherein the circuitry may be capable of configuring individual partitions or individual sectors as high-throughput storage or low-latency storage.

Solid state drive controller

Systems, methods, and computer-readable media may be provided for securely authenticating device identification and/or user identification for low throughput device-to-device wireless communication.
