Is Diffie–Hellman key exchange protocol vulnerable to man
What is the Diffie-Hellman Key Exchange? - Definition from Diffie-Hellman Key Exchange: The Diffie-Hellmann key exchange is a secure method for exchanging cryptographic keys. This method allows two parties which have no prior knowledge of each other to establish a shared, secret key, even over an insecure channel. The concept uses multiplicative group of integers modulo, which without knowledge of the Diffie-Hellman key exchange | Project Gutenberg Self Diffie-Hellman key exchange: lt;p|>||||| |Diffie–Hellman key exchange| (|D–H|)|||nb 1||| is a specific method of exchangin World Heritage Encyclopedia, the

The Diffie-Hellman key exchange algorithm solves the following problem: Alice and Bob wants to share a secret key for e.g. a symmetric key algorithm such as DES or AES, but they can only communicate through an insecure channel that is eavesdropped by their adversary Eve. I.e. all messages sent between Alice and Bob are observed by Eve. RFC 4419 - Diffie-Hellman Group Exchange for the Secure
Currently, the default protocol for key exchange is diffie-hellman-group-exchange-sha1. Using D-H as the key exchange provides perfect forward secrecy (PFS) for the SSH session. Figure 3.7 shows a packet capture from a SSH session. Note how the supported communication protocols are presented between the client and the server.

RFC 4419 - Diffie-Hellman Group Exchange for the Secure This memo describes a new key exchange method for the Secure Shell (SSH) protocol. It allows the SSH server to propose new groups on which to perform the Diffie-Hellman key exchange to the client. The proposed groups need not be fixed and can change with time. [STANDARDS-TRACK]
