Message Authentication Code (MAC) and HMAC - Cryptography - Cyber Security CSE4003

[@pritishn6350]

Watched multiple videos on HMAC explanation, finally found the ONE! TYSM Prof!

[@janepko]

Thank you Sir for the detailed explanation.

[@SatishCJ]

You are welcome

[@malikharith]

Thanks for sharing this video , detailed and clear concept about MAC and HMAC

[@TricoliciSerghei]

Wonderful explanation, thank you very much sir

[@sanjibkumarjena5556]

Thank you so much for the wonderful explanation. It was so helpful for me.

[@mohammednurirashid6729]

Thanks very much. This helps a lot

[@FaizBaig-f3d]

Hello Sir, Thank you very much for wonderfull video and would like to ask you one question that key uses in hmac is same key that aes or 3des uses for encryption or dh generate another shared secrect key for hmac

[@captainusman5349]

thanks for the video. Can you please tell me the drawbacks of implementing encrypt-then-MAC compared to other approaches? Thanks 🙂

[@jrmp20thlover]

Thanks for this series. Are you planning to do a short one about elliptic cryptography by any chance? :)

[@SatishCJ]

Sure..am trying to understand elliptic curves in depth. I will post a video soon on that . Thanks for the feedback

[@youstinagerges3054]

Yes, Thank you!

How do users share the secrete key between each other?

[@janepko]

Probably the shared secret key can be encrypted with asymmetric algorithm (RSA or ElGamal) and then send to other person. This is also known as public-key cryptography. E.g. GnuPG or PGP uses this or SSL/TLS to encrypt communication between a web browser and a webserver.

sir please can u provide this ppt ?

[@chrisadams27]

you said user A gets key, and sends it to user B, but that could be intercepted and this whole scheme fails
