Title : Perfect-Forward Secrecy for the Extensible Authentication Protocol Method for Authentication and Key Agreement (EAP-AKA' PFS)

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 [I-D.ietf-emu-rfc5448bis].
The extension, when negotiated, provides Perfect 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.
