At what modulus size does the logjam reduction stage become impractical?
Attacking a Diffie-Hellman exchange with logjam involves a massive precomputation effort once for the group, and then a comparatively simple reduction stage that is necessary to break each individual ...

What is the actual result of a Logjam's DH attack?
Does a Logjam attack calculate a group of probable Diffie-Hellman private keys for a user and then try them one at a time to see if it can decrypt the message - or does it directly calculate the one ...

Is it possible to generate backdoored DH parameters?
I know it has been already asked and answered whether it's possible to generate weak DH parameters.
But "recentely" we experienced the Logjam attack, which makes use of the pre-computation ...

Logjam-style attack on Factoring?
We're all aware of the Logjam attack, which is known as "FREAK on discrete logarithms". The attack works by doing a large pre-computation step, which needs only to be done once per field and then ...
