AES III - Advanced Encryption Standard - Introduction , Key Expansion in AES Cyber Security CSE4003

In this lecture we will be looking at the following concepts mentioned below
1. Block Diagram for Advanced Encryption Standard (AES)
2. Introduction to AES
3. Key Expansion algorithm in AES

Repetitive, exhaustive... perfect! There's no ambiguity in this lesson! Thank you!

[buse]

I was struggling with my own AES lecture notes but you can not image how helpful was this video thank you sir

[stefanabreu]

You are an amazing teacher. Thank you for your hard work!

[baharl]

this is the only explained key expansion very well.... can't thank you enough !

[akshayyeluru]

Best and clean video I have ever scene, Your Explanation is amazing

[BiddyutHasan]

I'm too privileged and learnt from your style of teaching. Actually I want to focus the AES in my upcoming research. I would be obliged if you suggest and support me by putting your exact point mention in AES to me at the earliest..

[ericzuckerburg]

Thank you very much; your explanations are very clear. thank you for showing the little details.

[thebigvusi]

There was no better way to explain this, you explained it very well thank you sir 🙏🏻

[JohnWickXD]

I can't thank you enough sir, May God bless you🥰

[rwxa_]

Thank you much Sir I had many doubts but your video cleard all of them ❤

[dxlorean]

great video sir like it alot much love

hi i have small doubt key 128 bit we converted 4*4 matrix with w0, w1, w2, and w3, but in key 256 what is the matrix size how to do key expansion

[shanky]

Hi,
Big fan of your video,
I have a small doubt, what are round constant and how are they calculated?

[deepasavant]

How words are converted to binary form

[ishaqahmad]

Its an amazing and excellent explanation. I have one question that is for round 1 you have selected round constant 1 in the constant table, for round 2 you have written round constant 2 then why not for round 3 the round constant should be 3 and for round 4 should have round constant 4 while there is 4 for round 3 and for round 4 is a round constant 8

[dxlorean]

Hello sir i need your help, what is the diffirence in the key expansion algorithms of aes128 and aes256?

[muhammadkashan]

Sir I mistake I'm plain text conversion at first during xor 12 byte answer is wrong

[RAJMOHAN-odfi]

Last state matrix has errors....if we do xor between message and expanded key we get below output
0, 16, 1a, 17
4, 1c, 0, 7
17, e, 3, 1
1b, f, 8, 10

In the last line instead of 8 your video shows 0f...i think that is wrong....can you check and correct it?

[krishnakishore]

Sir, It's very clear, Can I get PPT For AES ALGORITHM including round steps
Thank you

[gm]

Sir, What if the input data size is less than 128 bits?
