Techniques are disclosed relating to securing an accessory interface on a computing device. In various embodiments, a computing device detects a connection of an accessory device to an accessory interface port and, in response to the detected connection, evaluates a policy defining one or more criteria for restricting unauthorized access to the accessory interface port. Based on the evaluating, the computing device determines whether to disable the accessory interface port to prevent communication with the connected accessory device. In some embodiments, the computing device includes an interconnect coupled between the processor and the accessory interface port, and the interconnect includes a hub circuit configured to facilitate communication between a plurality of devices via the interconnect. In some embodiments, the computing device, in response to determining to disable the accessory interface port, instructs the hub circuit to prevent traffic from being conveyed from the accessory interface port.

Securing accessory interface

An authentication process for an endpoint device uses a pair of tokens. Tokens are generated at an authentication server that maintains a data store of token states, where the states are defined to include a 'normal' state sequence along which a token is expected to advance. The endpoint device can store a token pair in non-volatile local storage. To authenticate, the endpoint device can provide its stored token pair to the authentication server, which can determine whether authentication succeeds based on the states of the tokens in the token pair. After successful authentication, the authentication server can provide a new token pair to the endpoint device and advance the token states along the normal sequence. When the endpoint device confirms receipt of the new token pair, which replaces the previous token pair, the authentication server can advance the state of the tokens again.

Dual-token authentication for electronic devices

A graphical user interface ('GUI') can be presented on a remote control accessory device that has user input and display devices. The GUI can be defined and managed by a portable media device that is controlled using the GUI. The portable media device can provide the accessory with a GUI image to be displayed. The accessory can send information to the portable media device indicative of a user operation of an input device in response to the displayed image. The portable media device can process this input to identify the action requested by the user and take the appropriate action, which can include updating the GUI image provided to the accessory.

Embodiments disclosed herein provide for identification processes and/or procedures for accessories coupled with a mobile computing device. During identification an accessory can communicate lingo information that includes only those lingoes the accessory can use while coupled with the mobile computing device. The accessory can also communicate accessory protocol information to the mobile computing device during identification. The accessory can be limited to using only those lingoes and/or those protocols identified during identification. Various other accessory information, capabilities, preferences, etc. can also be communicated to the mobile computing device during identification.

Accessory identification for mobile computing devices

Sensor data is communicated between two electronic devices under control of the receiving device. For example, one device is equipped with one or more sensors that can produce a stream of real-time readings. The other device can request the sensor data from the first device and can also specify to the first device one or more throttling criteria to control or limit the amount of sensor data that is sent. Each throttling criterion can specify both a category of criterion (e.g., time-based, value-based, etc.) and a throttling parameter specific to the category. The first device can monitor the sensor data to determine when a throttling criterion specified by the second device is satisfied; when the throttling criterion is satisfied, the first device can send the current sensor reading as sensor data to the second device.

Communicating sensor data between electronic devices

A graphical user interface ('GUI') can be presented on a remote control accessory device that has user input and display devices. The portable media device can provide the accessory with a GUI image to be displayed. The accessory can specify the configuration of the remote GUI image and send that information to the portable media device. The portable media device can generate a GUI image based on the configuration and send the GUI image to the accessory. The accessory can display the GUI image on one part of its display and other information on another part of its display. The portable media device can define different GUI image types for use with different types of input controls of the accessory. Based on which input control is currently active, the portable media device can send the corresponding GUI image to the accessory for display on the accessory display.

An adapter can be used to connect a portable electronic device to an accessory in instances where the portable electronic device and the accessory have incompatible connectors. The adapter provides two connectors, one compatible with the portable electronic device and the other compatible with the accessory. The adapter has several modes of operation. The portable electronic device selects the appropriate mode of operation for the adapter once it receives information about the accessory connected to the adapter. The portable electronic device instructs the adapter to switch to the selected mode and in response the adapter configures its internal circuitry to enable the selected mode. The portable electronic device can then communicate with the accessory via the adapter. The presence of the adapter can be transparent to the accessory.

Efficiently managing visual information by small form factor electronic devices having limited display resources using a persistent overlay is described. The persistent overlay can be formed of selected visual information from a first page and can remain viewable over subsequently displayed pages.

Method and apparatus for managing visual information

A method for identifying an application usable with an accessory is provided. The method includes receiving an accessory identifier associated with the accessory, identifying an application protocol associated with the accessory identifier, identifying an application that supports the application protocol, and providing information about the application to a user device. A method for identifying an accessory usable with an application is also provided. The method includes receiving information about an application, determining an application protocol associated with the application, determining an accessory that supports the application protocol, and providing information about the accessory to a user device.

Method and system for locating an accessory and an application for use with a user device

Embodiments of the present invention provide various communication techniques for communication between a mobile computing device and an accessory. An accessory protocol that is generic to the mobile computing device can be used for some communication. An application executing at the mobile computing device can communicate with the accessory using an application communication protocol. In some embodiments, the application communication protocol can be different from the accessory communication protocol. In other embodiments the application protocol may only be recognized by the application and the accessory. In some embodiments, messages conforming to an application protocol can be communicated between the application and the accessory by packaging the messages inside a message conforming to the accessory communication protocol.
