For DH to be secure you want the Computational Diffie-Hellman Problem (CDH) to be hard which in turn implies that you want the Discrete Logarithm Problem (DLOG) to be hard as well.
WebMay 9, 2013 · For ephemeral Diffie-Hellman (DHE) cipher suites, the RSA private key is only used for signing the DH parameters (and not for encryption). These parameters are used in a DH key exchange, resulting in a shared secret (effectively the pre-master secret which is of course not visible on the wire). Wireshark supports various methods to …
