Method, apparatus and computer readable medium for initiating a secure device-to-device 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 in establishing a secure device-to-device connection (314) with a second computing device (304). The connection data comprises permission data, second address data and a second cryptographic key associated with the second computing device (304). Application data is selectively sent from the first computing device to the second computing device over the secure device-to-device communications channel, based on the received permission data. 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. |
