Abstract
There is provided a computer-implemented method for establishing a communication channel for exchanging messages securely between an initiator device and an endpoint device using an intermediary server. The initiator device is in communication with the intermediary server via a first session encrypted according to a cryptographic protocol. The endpoint device is in communication with the intermediary server via a second session encrypted according to a cryptographic protocol. A request for a handover token via the first session is sent to intermediary server. The handover token includes data that has been generated at the endpoint device and is configured to be used in setting up the communication channel between the initiator device and the endpoint device. The handover token is received from the intermediary server via the first session encrypted according to a cryptographic protocol. The communication channel is established between the initiator device and the endpoint device.
