DES b bta do

Thanks sir
The best AES video i watched so far

Sir how did you write S Box permutation table?
will they give the table or prepare our own like the table in video 16*16?

Why does 03 hex binary value keep changing from 0000 0011 to 0000 0110?

Is the round key already defined or we are manually setting it for our project? And X^8 = x^4+x^3+x right? 1 is not there yeah? Like 1 was already there before using irreducible polynomial

What a great explanation with slide show. Thanks a lot 👍👍

Awesome vid man - good work

Sir please make a video on how to generate a 128 bit key

thankyou so much

amazing dear, great explanation <3

very good explanation .👍 It is the best video for understanding AES 👍

Damn, really rigorous! Great explanation.

From where predefined matrix came? Whether it is given in question or we assume randomly in question?
Can anyone tell?

Best video.. ❤should have done key expansion also

sir
could u explain how did we get 47 for 01000111

I’ve never seen a perfect explanation like yours, thank you so much 🤍🤍🤍

Thanku Soo much..I searched all the lectures on you tube..but it was the best❤❤

WHERE IS YOUR ADD ROUND KEY

Thanks 😊

good job

watched this one night before examination. Explaned simply with good slideshow. Thank you sir.

sir, can u tell me how we got the round key in step 4, and can u please tell me the question for this example

Best video

Hii Sir , Vishwa here
Sir what u took the value of 46 in binary is wrong if we convert it into decimal its 70 the binary for 46 is 0010 1110

Literally amazingg ❤❤❤❤

Tysm Bhai, u made my day

Last step ma Round key matrix kasa aii Ya bata da😊

Es main 10 rounds pory ho gae hain hain sir

What a great explanation.

What a great explanation.

What a great explanation.

What a great explanation.

Can you in last step how ac 77 comes mean 47 xor AC how ac comes?

Thanks

This is amazing, thank god i found your video ❤

sir will the question be asked in the 4x4 matrix FORMAT like u mentioned in the beggining? (EA , 04) or a plaintext will be given in different format?

sir what was the plain text

thank you so much

To express *87 (decimal)* in *irreducible polynomial form* over \( GF(2) \), we need to:

1. *Convert 87 to Binary:*
87 (decimal) = *1010111* (binary).

2. *Interpret the Binary as a Polynomial:*
In **GF(2)**, each bit represents a coefficient of a polynomial. For example:
- \(1x^6 + 0x^5 + 1x^4 + 0x^3 + 1x^2 + 1x^1 + 1\).
- This simplifies to:
\(x^6 + x^4 + x^2 + x + 1\).

3. *Polynomial Representation of 87:*
The binary *1010111* corresponds to the polynomial:

\[
x^6 + x^4 + x^2 + x + 1
\]

---

### *Summary*

So, the irreducible polynomial form of *87 (decimal)* is:

\[
x^6 + x^4 + x^2 + x + 1
\]

This polynomial can be used in AES or other algorithms requiring operations over finite fields \(GF(2^8)\).

Thanks for this amazing explanation sir 🤒🤲💙

thanks g

was just gonna skip the video because of being so long but this was the best explaination i've got so far...thank you so much sir!

thank you very much sir

Sir can you give me the slides of this video plesse ?

Sir, how do you got round key matrix

Thanks

❤❤❤❤❤

Outstanding Explaination 100/100👌🏻
