C3TV - Logjam: Diffie-Hellman, discrete logs, the NSA, and you

C3TV - Logjam: Diffie-Hellman, discrete logs, the NSA, and you

Earlier this year, we discovered that Diffie-Hellman key
exchange — cornerstone of modern cryptography — is less
secure in practice than the security community believed. In this
talk, we’ll explain how the NSA is likely exploiting this weakness to
allow it to decrypt connections to at least 20% of HTTPS websites, 25% of SSH servers, and 66% of IPsec VPNs.

Lol, this was my last lecture of the second day. I was listening to it while my caregiver was here, so she got to hear all about how the NSA is possibly breaking Diffie-Hellman too!
