Keep in mind that libraries, internet cafes etc aren't going to be keen on you turning up with some (to them) random USB stick and wanting to reboot their pride-and-joy off it. I suspect your choices are to either use OPIE (or some adaption thereof) with ssh on an untrusted computer and assume that anything you type will be logged or carry your own trusted computer and use some form of wireless (3G, NextG etc) to communicate with your systems. Note that using very large sequence numbers should slow down an attacker (though only linerarly) since they still need to iterate MD5 by that many rounds. --=20 Peter Jeremy --m51xatjYGsM+13rf Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (FreeBSD) iEYEARECAAYFAkmTE80ACgkQ/opHv/APuIf4FACdGz/PEfj14bVhQaUoM51/0Di4 AAoAniv8BiK94fTwH7v4QoJeTbR8CNsq =t+Bx -----END PGP SIGNATURE----- --m51xatjYGsM+13rf--
