Dear All

I am going to implement ppp authentication for mobile IPv6 communication. I have implemented EAP ( MD5-Challenge ).

But i am not able to understand about AKA , How can i use PPP message format with AKA? If it is like EAP what is protocol field and length and optional field.

USIM will work like a client .what should be the fuctionality of authenticator(server)?

The use of the AKA also as a secure PPP authentication method in devices that already contain an USIM. 
AKA typically runs in a UMTS Subscriber Identity Module (USIM), a smart card like device. 

Five security feature groups are defined. Each of these feature groups meets certain threats and accomplishes certain security objectives:

- Network access security : the set of security features that provide users with secure access to 3G services, and which in particular protect against attacks on the (radio) access link;

- Network domain security: the set of security features that enable nodes in the provider domain to securely exchange signalling data, and protect against attacks on the wireline network;

- User domain security : the set of security features that secure access to mobile stations;

- Application domain security : the set of security features that enable applications in the user and in the provider domain to securely exchange messages;

- Visibility and configurability of security (V): the set of features that enables the user to inform himself whether a security feature is in operation or not and whether the use and provision of services should depend on the security feature.

Thanks
