Abstract
A machine implemented method of authenticating a communication channel between a first device and a second device by providing proof of proximity between both devices, the method comprising: generating, at the first device, an acoustic authentication signal to be received at the second device via a solid body acoustic coupling established between the first device and the second device thereby providing proof of proximity between both devices and so authenticating the communication channel between the first device and the second device.
