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 memo replaces the specification of EAP-AKA'. EAP-AKA' was > defined in RFC 5448 and updated EAP-AKA RFC 4187. As such this > document obsoletes RFC 5448 and updates RFC 4187. > > 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.
