Crypto researchers: Time to use something better than 1024-bit encryption

It’s actually possible for entities with vast computing resources – such as the NSA and major national governments - to compromise commonly used Diffie-Hellman key exchange groups, so it’s time for businesses to switch to something else like elliptic curve cryptography, researchers say.
“It’s been recommended to move from 1024-bit [encryption] for a long time, and now there are very concrete risks of not doing that,” says Nadia Heninger, an assistant professo
