The Logjam attack against the discrete logarithm
Participants : Pierrick Gaudry, Emmanuel Thomé [contact] , Paul Zimmermann.
Together with colleagues from the Prosecco project-team and with other colleagues, we exhibited a new attack again the TLS protocol when using discrete logarithms [15] . A proof-of-concept of the attack was demonstrated using the CADO-NFS software. This paper obtained the best paper award at the ACM CCS 2015 conference, and received significant media coverage both in the specialized and non-specialized press.
