Abstract:
The 3GPP Mobile Network Authentication and Key Agreement (AKA) is an
authentication mechanism for devices wishing to access mobile
networks. RFC 4187 (EAP-AKA) made the use of this mechanism possible
within the Extensible Authentication Protocol (EAP) framework. RFC
5448 (EAP-AKA') was an improved version of EAP-AKA.
This document is the most recent specification of EAP-AKA',
including, for instance, details and references about related to
operating EAP-AKA' in 5G networks.
EAP-AKA' differs from EAP-AKA by providing a key derivation function
that binds the keys derived within the method to the name of the
access network. The key derivation function has been defined in the
3rd Generation Partnership Project (3GPP). EAP-AKA' allows its use
in EAP in an interoperable manner. EAP-AKA' also updates the
algorithm used in hash functions, as it employs SHA-256 / HMAC-
SHA-256 instead of SHA-1 / HMAC-SHA-1 as in EAP-AKA.
This version of EAP-AKA' specification specifies the protocol
behaviour for both 4G and 5G deployments, whereas the previous
version only did this for 4G.
