The method also includes selecting a random port number and creating a session key if the intelligent client device access rights are authenticated and validated, causing the random port number and the session key to be encrypted via the first encryption means, transmitting the encrypted random port number and session key to the intelligent client device, and detecting establishment of {HEAD ~ a second connection} between the intelligent client device and {TAIL ~ a random port} corresponding to the random port number
