Re: CBC makes Implementations too Slow.



Maybe I'm missing something, but packets are sent in a bit-serial manner
in almost all cases; you can be encrypting block n+1 while you are
transmitting the (already encrypted) block n.  Since you have to transmit
some headers in the clear, you can start encryption of the payload at the
same time as the cleartext headers are being transmitted; so long as 
you can encrypt at line speeds, you keep the pipelines full.  Isn't that
what we want?
