Abstract
There is presented a method, a computing device and a computing system for establishing secure communication between computing devices. A method for a first computing device to establish trusted communication with a second computing device comprises the first computing device sending a request to create a secure channel to the second computing device, the request comprising a first cryptographic element and a device identifier. The first computing device receives a channel identifier from the second computing device in response to the request, and a notification over a secure channel using the device identifier, the notification comprising a channel identifier and a second cryptographic element. The first computing device compares the channel identifier received in the response to the request and the channel identifier received in the notification and, if the first computing device determines that the two channel identifiers match, the first computing device deriving a secret key using the first cryptographic element and the second cryptographic element.
