The invention relates to a technique of pairing a device (10-12) with a co-ordinating entity (20) of a private wireless network (1). The co-ordinating entity obtains an identifier of the device to be paired and a temporary network identifier specific to the device. The co-ordinating entity then configures itself on standby awaiting the device identified on the temporary network. The device to be paired transmits a request for association with the temporary network to the co-ordinating entity on the temporary network. The co-ordinating entity verifies that the device that transmitted the request for association corresponds to the device identified and then transmits to it on the temporary network an encryption key associated with the private wireless network and an identifier of the private network, then instructs a toggling of the device from the temporary network to the private wireless network. The device to be paired then restarts on the private network and transmits a request for association to the private network on the private network. The co-ordinating entity and the device identified are then associated.
