In a DHE attack, a malicious client initiates a cryptographic handshake, falsely claiming to support only the ephemeral variant of the Diffie-Hellman key agreement protocol (DHE), which prompts the server to generate a key pair and compute a shared secret, both of which require computationally intensive modular exponentiation operations.  The malicious client avoids performing these … Continue reading D(HE)at Attack: 20-Year-Old Diffie-Hellman Flaw Lets Hackers Overheat Your CPU
