4.1 Introduction
e17efbe6bcd60372b406ce35b2ebc2c9
103 458
4.1.1 Scenario
This solution presents an alternative mechanism to conceal permanent or long-term subscription identifier when a temporary subscription identifier is not available (c.f. initial Attach Request in LTE). Information provided over the air during initial attach request in LTE can allow a passive eavesdropper to obtain a va...

4.1.2 Preliminary considerations
A major problem in current mobile networks is that identifiers are occasionally exposed in situations where no security context (i.e. shared cryptographic material) is available, neither to authenticate identity requests, nor to protect (encrypt) the IMSI in the identity response, as well as in attach request messages,...

e17efbe6bcd60372b406ce35b2ebc2c9
103 458
4.3.1 Stakeholders
A 3GPP mobile network architecture [i.3] is assumed. In particular, the following roles are defined: • Home Network: is the central source for mobility services to the subscriber. The subscriber has a direct subscription with the Home Network: an identity for the subscriber has been allocated before any access to the n...

4.3.2 Preconditions
Relying on a trusted hardware, the Trusted Authority (TA) securely generates the master secret key (MSK), the global master public key (MPK), and the corresponding secret keys according to a selected large universe ABE scheme. As the TA uses a large universe ABE scheme, secret keys can be generated initially or in real...

4.3.3 Trigger
The UE tries an Initial Attach request to the Visited Network.
e17efbe6bcd60372b406ce35b2ebc2c9
103 458
4.3.4 Flow of events
The Visited Network broadcasts (continuously) its assigned attributes together with its network identifiers (MCC and MNC). The UE encrypts the subscription identifier (IMSI) according to an ABE scheme by using the global public key MPK and the attribute received in broadcast over the air (the attribute identifying the ...

4.3.5 Exit Condition
The Authentication Vector is returned to the Visited Network. The standard 3G/4G/5G authentication procedure between the UE and the Visited Network is finally executed.

4.3.6 Security Aspects
In the 3G/4G/5G system, the network identifiers (MCC, MNC) of the participating network operators are assumed to be publicly known. The trust framework is regulated by inter-operator roaming agreements, and the involved operators are trusted to function accordingly, because of their business interests. In the case of A...

4.3.7 Recommended ABE scheme
The CCA-secure KP-ABE with KP-FAME-KEM [i.21] ABE scheme should be used.
