Abstract: The invention provides a telecommunications system comprising a core network (1), an Integrated Access Backhaul donor (2) arranged in connection with the core network (1); and a plurality of Integrated Access Backhaul nodes (4) connected to one Integrated Access Backhaul donor (2), either directly or by means of other Integrated Access Backhaul nodes (4). At least some of the Integrated Access Backhaul nodes (4) are configured to operate in different backhauling profiles, and at least some of these Integrated Access Backhaul nodes (4) comprise a UICC (6) which is configured to manage a set of backhauling profiles of the corresponding Integrated Access Backhaul node (4).

Abstract: The invention concerns a method for preventing transmission of hidden information in a communication channel during a telecommunication terminal authentication phase, said method comprising: - Transmitting from a telecommunication terminal cooperating with a secure element 10 to a visited PLMN 11 a unique identifier of the secure element; - Generating at the visited PLMN 11 a required information REQ_INFO and sending the unique identifier and the required information REQ_INFO to a home PLMN 12 identified by a MCC/MNC comprised in the unique identifier; - At the home PLMN 12, generating a random value RAND2 and computing a cryptographic value RAND* based on the random value RAND2 and the required information REQ_INFO; - At the home PLMN 12, generating an authentication vector AV based on the cryptographic value RAND* and the long term key of the secure element, the long term key being associated to the unique identifier, and sending the authentication vector AV and the random value RAND2 or only the authentication vector AV containing the random value RAND2 instead of the cryptographic value RAND* to the visited PLMN 11; - At the visited PLMN 11: o If the home PLMN 12 has sent the authentication vector AV and the random value RAND2, computing a cryptographic value vRAND* from the required information REQ_INFO and the random value RAND2, verifying that the cryptographic value RAND* received in the authentication vector AV corresponds to the cryptographic value vRAND* computed at the visited PLMN 11 and, if yes, transmitting from the visited PLMN 11 to the telecommunication terminal 10 the cryptographic value RAND* and the authentication token AUTN retrieved from the authentication vector AV; o If the home PLMN 12 has sent only the authentication vector AV containing the random value RAND2 instead of the cryptographic value RAND*, computing another cryptographic value RAND* from the required information REQ_INFO and the random value RAND2, and transmitting from the visited PLMN 11 to the telecommunication terminal 10 the other cryptographic value RAND* and the authentication token AUTN retrieved from the authentication vector AV.
