I participate in IT smart grid standardization within IEC TC57 WG15. A
couple of standards under development still allow 1024 bit RSA keys for
so-called backward compatibility. I have so far not been able to change
that. My question is now. Is there any information available for how long
time or how much effort it takes to break  a 1024 bit RSA key?
