Hi Jessie, The strongswan implement the 3GPP2 EAP-AKA algorithm. And OP && OPC is used in 3GPP EAP-AKA algorithm. These two algorithms are different. About 3GPP EAP-AKA, you can refer to the standard "3GPP TR35206-600" and 3GPP2 EAP-AKA, you can refer to the standard "S.S0055".

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.
