Abstract:
Many different attacks have been reported as part of revelations
associated with pervasive surveillance. Some of the reported attacks
involved compromising smart cards, such as attacking SIM card
manufacturers and operators in an effort to compromise shared secrets
stored on these cards. Since the publication of those reports,
manufacturing and provisioning processes have gained much scrutiny
and have improved. However, the danger of resourceful attackers for
these systems is still a concern.
This specification is an optional extension to the EAP-AKA'
authentication method which was defined in [RFC9048]. The extension,
when negotiated, provides Forward Secrecy for the session key
generated as a part of the authentication run in EAP-AKA'. This
prevents an attacker who has gained access to the long-term pre-
shared secret in a SIM card from being able to decrypt any past
communications. In addition, if the attacker stays merely a passive
eavesdropper, the extension prevents attacks against future sessions.
This forces attackers to use active attacks instead.
