A secure wireless communication link (pairing) between two devices can be established using cleartext wireless transmissions between devices not joined to a network (“probes”). One device can broadcast a first probe indicating that it is seeking to establish a pairing. The other device can respond with a second probe, and the two devices can establish a shared secret, e.g., by exchanging further information using additional probes. Thereafter, either device can send a message to the other by encrypting the message using a cryptographic key derived from the shared secret; encrypted messages can also be sent within probes. The receiving device can extract an encrypted message from a probe and decrypt it using the cryptographic key. The encrypted message can include credentials usable by the receiving device to join a wireless network.

A method and apparatus for virtual private network (‘VPN’) liveness checking, the method, upon expiration of a timer, sending, over a VPN tunnel, a request to a server located behind a terminator of the VPN; checking whether a response to the request is received within a time interval; if a response to the request is received, resetting the timer; and if a response to the request is not received within the time interval, resending the request if a request count is less than a set number of requests; or providing an inactive tunnel indication to a VPN client manager if the request count equals the set number of requests.

This document describes, inter alia, techniques for configuring or setting up a wireless device. As an example of the features described herein, a first wireless device may be used to configure a second wireless device as follows: the first wireless device may detect that the second wireless device is available and is configurable; the first wireless device may connect to the second wireless device and transmit configuration information to the second wireless device, where the configuration information includes credentials that may be used to access a wireless network (e.g., a password to access a Wi-Fi network); the first wireless device and the second wireless device may then both connect to the wireless network, using the credentials; once both devices are connected to the wireless network, the first wireless device may verify that the second wireless device has been correctly configured.

Configuring wireless accessory devices

A system and method are used to connect an installed device to a local premise network, such as a home network provided by a router in the home. A user may use a host device, such as a mobile telephone that is already connected to the home network to provide the home network credentials to the installed device without having to enter the home network credentials manually into the installed device such as a thermostat.

Provisioning credentials for embedded wireless devices

A wireless communication apparatus includes a receiving unit configured to receive a response request signal, a transmitting unit configured to transmit a response signal in response to the response request signal, a measuring unit configured to continuously measure received power of the response request signal received by the receiving unit, and a communication control unit configured to cause the transmitting unit to transmit the response signal to a wireless communication apparatus that has transmitted the response request signal if the received power of the response request signal is higher than a threshold value.

Methods and apparatus that enable solicited access to a secure wireless network having complex security protocols. In one embodiment, such solicited access is performed using a streamlined or reduced number of steps and includes an exemplary active/passive scanning protocol and use of an optimized service discovery protocol (SDP). Furthermore, multiple aspects of the invention are directed to improving and enhancing user experience, including a reduction of “human” interaction requirements for secure network operation (such as changing settings, entering addresses, etc.), and furthermore, integrated utilization of human readable text.

A method for pairing an accessory with a host device includes placing an output device of the accessory into a randomly selected state N-times. The information about the current state of the accessory is provided to a host device after each state selection for N number of times. Thereafter, the host device generates an authentication code based on the N inputs and the accessory generates another authentication code based on the N selected states. The authentication codes can be then compared and can be used to “pair” the host device and the accessory, allowing secure communication.

Methods and systems for associating, in a secure manner, a link between web sites (or other network resources) and installed applications. In one embodiment, a signed list of one or more URLs is downloaded and validated to establish an association, which is stored in a data structure, between a first application and a second application. In response to receiving a selection of a URL in the second application, comparing the selected URL to URLs in the data structure and displaying, in the first application, content of the selected URL in response to determining that at least a prefix portion of the selected URL matches one of the URLs associated with the first application in the data structure.

A Wireless Local Area Network (WLAN, 102 fig. 1) employing the Wi-FiTMProtected Setup (WPS) protocol scans wireless Access Points (AP, 106) both passively and actively (202) using an optimized Service Discovery Protocol (SDP) in order to reduce the number of steps and user-inputs to secure the link, requiring no security-dedicated user interface. "Thin" devices (104E) may freely solicit access to wireless networks and discover whether Solicited Activation of Wi-Fi Protected Setup (SAW or EasyConnect) is supported (204) via flag bits (fig.4), filtering out access points which do not allow abbreviated WPS connection. Passive scanning is used on channels for which active scanning is prohibited by Dynamic Frequency Selection (DFS), with passive scans receiving beacon signals and active scans transmitting probe requests (fig. 3).
