Agreed, crypto offers recognition of previous encounters. A desire to make
exchanges that traverse LSNs is clearly where something like Kerberos tickets
can play a suitable role in offering a low overhead process. Kerberos can
also offer a lower frequency rate where it remains practical to identify all
domains prior to issuing tickets. Reputations MUST BE based on AUTHENTICATED
identities. Clearly, IPv6 makes use of IP Addresses as an identifier
unsuitable.
None of which has anything to do with the subject line. Please take it to a
spam filtering or reputation thread.
