Are you are talking about a EAP-AKA algorithm to calculate quintuplets? > what is the purpose of these two fields? I have never heard of them, but EAP-SIM/AKA can use any proprietary algorithm to calculate authentication data. > they are configured in the operator side? and where can i > found in the strongswan source codes? You can't. We have a software implementation of the 3GPP2 standard for EAP-AKA (implemented in that eap-aka-3gpp2 plugin), but your algorithm is different. You'll probably have to provide your own backend implementing the algorithm you need for your application.
