Abstract METHOD OF ESTABLISHING A CRYPTOGRAPHIC KEY, NETWORK HEAD AND RECEIVER FOR THIS METHOD, AND METHOD OF TRANSMITTING SIGNALS This method of establishing a cryptographic session key comprises: a subscription phase (104) during which an identifier of a local loop to the end of which a receiver must be connected is acquired, and an authentication step comprising: a) an operation (142) of automatically obtaining an identifier of the local loop to the end of which the receiver is actually connected, and b) an operation (146) of verifying that the identifier obtained during the operation a) corresponds to the identifier acquired during the subscription phase so as to authenticate the receiver.
