Embodiments of the invention is directed to a method for connecting a device to a network. An example method comprises providing a device assigned with a device identifier and an asymmetric cryptographic key pair that includes a public key and a private key. The device stores the private key on a memory thereof. The device is provided with information as to the assigned device identifier and/or the public key. This information is detectable by a detector so as to be transmissible to a server for it to identify the device identifier and the public key assigned to the device.
