A method includes receiving, by a mobility management entity (MME), a redirection request message from an access and mobility management function (AMF) node, where the redirection request message includes key-related information. The method also includes generating, by the MME, an encryption key and an integrity protection key based on the key-related information. The redirection request message is used to request to hand over a voice service from a packet switched (PS) domain to a circuit switched (CS) domain.

Embodiments are disclosed that allow encrypted data to be sent between a Bluetooth enabled device and a virtual device associated with a corresponding physical device. In particular, a Bluetooth implementation on the physical device may include one or more raw interfaces to facilitate endpoint to endpoint secure Bluetooth cryptography. Using these raw interfaces, an encrypted Bluetooth channel may be established directly between the virtual device and the Bluetooth enabled device using the radio of the physical device, where data may be encrypted and decrypted at an endpoint of the Bluetooth communication channel (such as at the virtual device or the Bluetooth enabled device) and passed through a Bluetooth implementation on the physical device without any additional encryption or decryption being performed on that data.

An authentication system facilitates a transfer of enrollment in authentication services between client devices. The authentication system enrolls a client device in authentication services to enable the client device to be used for authenticating requests to access one or more services. As part of enrolling the client device, the authentication system receives authentication enrollment information for the client device that is associated with one or more authentication credentials securely stored on the client device (e.g., a multi-factor authentication (MFA) certificate). The authentication system facilitates one or more processes for transferring the enrollment from an enrolled client device to a non-enrolled client device that limit the number and complexity of actions performed by the user. In particular, the authentication system facilitates transfer of enrollment based on receiving enrollment transfer requests authorized by the enrolled client device using one or more authentication credentials associated with the enrollment of the enrolled client device.

A method, computer-readable storage device and apparatus for encrypting a broadcast message of a base station are disclosed. For example, the method selects an encryption key for the broadcast message and encrypts the broadcast message using the encryption key to create an encrypted broadcast message. The method then transmits an identifier of the encryption key and transmits the encrypted broadcast message over a broadcast channel. A method for decrypting a broadcast message that is encrypted is also disclosed.

A method and apparatus for configuring a bi-directional channel in a wireless communication system is provided. A user equipment (UE) configures the bi-directional channel which is used for either an uplink (UL) channel or a sidelink (SL) channel, and transmits data via at least one of the UL channel or the SL channel. The bi-direction channel may be used for vehicle-to-everything (V2X) communication.

Systems and methods for token processing are disclosed. An access device can provide access device data to a mobile communication device. The communication device generates a token request including the access device data and communication device data and sends the token request to a server computer. The server computer returns a token and a token cryptogram to the mobile communication device. The token and the cryptogram may be used in a transaction.

Encryption keys for an enterprise are stored at a perimeter device such as a gateway, and rules are applied at the network perimeter to control whether and how these keys are used for cryptographic processing of communications passing through the perimeter device. The encrypted status of communications, e.g. whether and how files are encrypted with the encryption keys, may also be used to assist in selecting appropriate security handling and routing of the communications.

In general, in one aspect, a method includes receiving software code with an invalid characteristic, repeatedly attempting to execute the software code with the invalid characteristic on a device, and in response to successful execution of the software code with the invalid characteristic, taking an action. The action may include an action to remediate the device.

The disclosure details the implementation of an apparatus, method, and system comprising a portable device configured to communicate with a terminal and a network server, and execute stored program code in response to user interaction with an interactive user interface. The portable device contains stored program code configured to render an interactive user interface on a terminal output component to enable the user the control processing activity on the portable device and access data and programs from the portable device and a network server.

The various implementations described herein include methods, devices, and systems for detecting motion and persons. In one aspect, a method is performed at a smart home system that includes a video camera, a server system, and a client device. The video camera captures video and audio, and wirelessly communicates, via the server system, the captured data to the client device. The server system: (1) receives and stores the captured data from the video camera; (2) determines whether an event has occurred, including detected motion; (3) in accordance with a determination that the event has occurred, identifies video and audio corresponding to the event; and (4) classifies the event. The client device receives information indicative of the identified events, displays a user interface for reviewing the video and audio stored by the remote server system, and displays the at least one classification for the event.
