-- Sec 4.1:
128-bit ciphers are expected to remain secure for at least several years,
and
256-bit ciphers "until the next fundamental technology
breakthrough".
Is the quoted text quoting something? If not, why is it in quotes?
To my knowledge, that is not a quote from another text, but I will
double-check with my co-authors. Conceptually it could refer to
something like a special-purpose "sieving machine" of the sort mentioned
in RFC 3766.
This is from Bruce Schneier: "In fact, we cannot even imagine a world
where 256-bit brute force searches are possible. It requires some
fundamental breakthroughs in physics and our understanding of the
universe." But personally, I would remove the quotes.
Thanks,
Yaron
