This is more of a request to change the TLS protocol, than an enhancement to OpenSSL.
DHE and ECDHE ciphers provide PFS to protect against compromised public key-pairs. However, if a MITM has the same certificate, signed by a trusted certificate authority, then most bets are off. Client-authentication can provide additional protection against MITM attacks, and allow servers to identify if a MITM is interfering with a valid user. -- -Todd Short // tsh...@akamai.com<mailto:tsh...@akamai.com> // “One if by land, two if by sea, three if by the Internet."

In the event the MITM has the same certificate(SSL - offloader) then the data can be encrypted/decrypted. Would like to know if we can have the enhancement of using random key pair, generated form each certificate, so that each SSL handshake would make use of a random key-pair, and thereby give a different key value to each encryption -decryption, and therby be able to determine if the MITM with a same certificate has decrypted & encrypted data.
