Why not just go with 256-bit EC (128-bit symmetric strength)? Is the 8 bytes
per signature the issue, or the extra compute time?

By the way, we've recently been planning our next crypto-capabilities
design for the TahoeLAFS secure distributed filesystem. This
involves deciding whether a 192-bit elliptic curve public key is
strong enough, as well as subtler and more unusual issues involving
embedding keys directly in

Subsequent expansions in computing power will involve breaking up
Jupiter to build really big computers, and so forth, which will slow
things down a bit.
So 144 bit EC keys should be good all the way to the singularity and

First of all congratulations to the team a
Hi all,
We are pleased to announce that we have set a new record for the elliptic
curve discrete logarithm problem (ECDLP) by solving it over a 112-bit
finite field. The previous record was for a 109-bit prime field and
dates back from October 2002.

Hi all,
We are pleased to announce that we have set a new record for the elliptic
curve discrete logarithm problem (ECDLP) by solving it over a 112-bit
finite field. The previous record was for a 109-bit prime field and
dates back from October 2002. Our calculation was done on a cluster of
