I found this article that claims asymmetric crypto signature of DH-obtained key prevents MITM: http://www.gremwell.com/ssh-mitm-public-key-authentication Key idea: The value of 'signature' is a ...
I've seen an application recently that used the Diffie Hellman algorithm. It is not a Ephemeral Diffie-Hellman implementation, but rather a Diffie Hellman one. After the secret keys have been ...
How can DH provide a known secret to two parties over an unencrypted connection without it being intercepted via MITM?
Without using Private and Public keypairs, i do not understand how Diffie-Hellman is able to generate a secret key between two parties on the internet without passing something between that could be ...
I'm looking at a system that uses an unprotected Diffie-Hellman exchange to negotiate a key for the session encryption. That Diffie-Hellman is not secure against man-in-the-middle attacks is textbook ...
I understand how DH key exchange is vulnerable to a MITM attack. When Alice sends Bob g, p and her public key, if she also sent a value H that was a hashing of the values g,p, and public key all ...
