Secure communication channels

摘要

Initiating a secure device­-to-device D2D communications channel 314 between a first computing device 302 and a second computing device 304. According to the method, a first computing device 302 sends a connection request comprising a first cryptographic key and first address data associated with the first computing device 302 to a server 120. The connection request is sent over a first secure communications channel 308 established between the first computing device 302 and the server 120. In response, the first computing device 302 receives, over the secure communications channel 308, connection data from the server 120 for use inestablishing a secure device-to-device connection 314 with a second computing device 304. The connection data comprises second address data and a second cryptographic key associated with the second computing device 304. The 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 (NFC) and Wi-Fi. The first computing device comprises a secure application and the secure device-to-device communications channel is established between the secure application and the second computing device.
