Negotiating a secure device-to-device communications channel 314 between a first computing device 302 and a second computing device 304. According to a method, a server 120 receives first and second connection requests from the respective first and second computing devices 302, 304. The connection requests include address data and a cryptographic key associated with the respective sending computing devices and are sent over secure communications channels 308, 310 between the computing devices 302, 304 and the server 120. To facilitate establishment of the secure connection 314, the server 120 sends the first connection data to the first computing device 302 and second connection data to the second computing device 304. The first connection data includes the address data and cryptographic key associated with the second computing device 304, and the second connection data include the address data and cryptographic key associated with the first computing device 302. The first connection request indicates a communications medium for establishment of the secure device-to-device communications channel, and may be one of Bluetooth, a local area network, Near Field Communication and Wi-Fi. The medium for establishment of the secure device-to-device channel is different from the medium associated with the first and second secure communications channels. |
