Just to be crystal clear -- I believe you mean the stated order of the
steps, not the keys within the steps.  Is that correct?

In otherwords, in step 2, after the target has received CHAP_A=<A1,A2,...>
from the initiator, the target can reply with any of the 3 keys
CHAP_A=<A>
CHAP_I=<I>
and
CHAP_C=<C>
in any order within 1 pdu,
or in 3 pdus, each carrying 1 key (but it doesn't matter which key
is in which pdu)
or in 2 pdus, one carrying one key (doesn't matter which key)
and the other carrying the other 2 keys (doesn't matter which order),
etc.

This makes sense because this is all the same step.
What cannot happen is that the target would send any of these
keys before receiving CHAP_A=<A1,A2,...> from the initiator,
nor could the target send CHAP_N or CHAP_R to the initiator
before the initiator completes its next step, which would be
to send CHAP_N and CHAP_R to the target.

Is this correct?

Thanks,
