Hi,

The question is based on WPA-1(3.1). I am trying
develop WPA-AES-CCM client using PSK information.

The WPA requires the EAPOL handshake to be carried
out. Now if I were to use version # 2 (AES-CBC-MAC),
the standard doesnt specify any way of computing the
MIC. It just states MIC is calculated using
AES-CBC-MAC. Any insights on as to how is the
AES-CBC-MAC (RFC3610) is used. A nonce and addition
authentication data is required to run AES-CBC-MAC
over the EAPOL frame. Any pointers/hints on how to
form these or bypass these.

Regards
Jitesh
