The reference to the EAP methods convinces me this is no worse than an existing thing, but not (by itself) that it is cryptographically sound, so I just wanted to check as I think prf(SK_pr,IDr') has until now been calculated but not transmitted, so there's a tiny change here maybe, but as I said I didn't have time to fully check. If someone just tells me that yes, the authors/wg did consider this, that'll be fine, no need to fully explain to me why using SK_pr like this is safe (though if you want to, that'd be fine too). - 2.5: "hand out" is an odd phrase here - would be better to expand on that I think and say more precisely what should never be done. _______________________________________________ IPsec mailing list IPsec@ietf.org https://www.ietf.org/mailman/listinfo/ipsec
