As I understand SIG(0), the home user would have to generate a public/private key pair and securely transmit the public key to their ISP. Frankly, it would be easier to use TSIG and use something based on the user name and password - which home users have for checking their e-mail if nothing else - as the secret key. But the important implication is that each host will have to implement DDNS, and that the home user will have to know enough to configure their equipment with the secret somehow. I don't necessarily think this is bad, but AFAIK nobody has even proposed the IETF make such a suggestion. -- Shane Kerr RIPE NCC #---------------------------------------------------------------------- # To unsubscribe, send a message to <[EMAIL PROTECTED]>.
