Before Alice and Bob can start calculating Ya and Yb, they need to have a public "exchange of secrets" session with (a, q) to ensure they're both on the same page.
Thank you so much....!!!! I am very glad to hear that.... Your words motivate me lots... Please share with others.... Please susbcribe my channel.... Please follow my blog: chiragbhalodia.com
I love the fact, that you suggest using HTTPS as a solution to savely generate a shared key, with Diffie-Hellmann. Because in essence HTTPS uses RSA to generate a shared key, wich is then used to encrypt the Messages between Alice and Bob so that they can communicate, without a 3rd Party interfering the messages. And over this secure connection, you would then calculate an other key with Diffie-Hellmann wich is your second shared secret (after the RSA key for HTTPS). So why simply dont use Diffie-Hellmann and use RSA for key Exchange?

was expecting for ways of Preventing MITMA in Diffie-Hellman to have been more on how to advance the protocol eg by use of authentication certificates or something.
Yeah... Difie-Hellman is not protect against MITM... Some authentication protocols is required to exchange the key....else use kerberos scenario or needham schroeder protocols... Please subscribe my channel.... Please follow my blog: www.chiragbhalodia.com/p/network-security.html
RSA is used in encrypt the text and diffie hellman mostly used fo key generation... Sorry for late reply... Please sshare with others... Please subscribe my channel... Please follow my blog: chiragbhalodia.com

WTF... this means diffe hellman key exchange is completely useless. I thought diffe hellman key exchange sole purpose was to prevent a man in the meddle attack even when there is one occurring. The secret key is what makes the data un readable by the attacker. from my understanding the attacker takes both parties' public key and provides them the with an attacker public key... that is just slick and scary...
Dear Ayush, Watch video properly, step by step. You can get your answer. Still you cannot get answer then ask me again.... Its very easy.... Darth is capture messages from both sides .... For example, Alice think that she is communicate with bob (but actually he is darth) and same way at bob side.
