(and we used VIA C5P dual RNG processors to provide the manual keying material that was kept in sync between a pair of communicating stations over unencrypted 802.11b - there was no IKE or other public key exchange, just synchronized symmetric ciphers and digests) ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://ativel.com http://postbiota.org AC894EC5: 38A5 5F46 A4FF 59B8 336B 47EE F46E 3489 AC89 4EC5
