Exam CISSP-ISSAP topic 1 question 31 discussion

D. Diffie-Hellman Diffie-Hellman is a key exchange protocol that allows two parties to establish a shared secret key over an insecure communication channel without any prior secrets. However, it does not provide authentication of participants, making it vulnerable to man-in-the-middle attacks. A. Blowfish and B. Twofish are symmetric encryption algorithms and are not directly related to the key exchange process or vulnerability of Man-in-the-Middle attacks. C. RSA is an asymmetric encryption algorithm commonly used for secure communications but is not specifically associated with the key exchange process vulnerable to MITM attacks.

D. Diffie-Hellman Diffie–Hellman key agreement itself is a non-authenticated key-agreement protocol
