Bro you are Good in explanation, for real you are a ocean of knowledge I was struggling with this topic and u just explained it so clearly, I am telling u, you are great we need professors like you, you put your heart in explanation u really make sure we understand that, Thank you soooo much I been reading whole day and it wasn’t clear, but after watching ur video it’s all good

[Akashkumar-eitm]

Best explanation..! It took me 2-3 hrz to study from book but with this it's just a work for 20 minutes.. amazing

[Lahitha]

wasted half of my day in understanding this by books! you are amazing... got understood in half an hour.. wishing you lots of success :)

[tanishaashar]

You are a blessing in disguise for all us engineers!

[sulbhasingh]

Finally got the best explanation after watching lots of lecture on this topic...👍👍

[rajeshkhatwani]

Pure Genius! It's one thing to understand the concept but it's completely different thing altogether to make someone else understand the concept, it requires deep level of understanding. Just when I thought DES algorithm video was best, this surpassed all my expectations. You are incredible educator and the passion and the enthusiasm for sharing the knowledge and making people understand with utmost clarity can be seen by your videos. Sheer magic! ✨

The Advanced Encryption Standard (AES) algorithm is a widely used symmetric key encryption algorithm that plays a significant role in modern cryptography and network security. AES is also known as Rijndael, named after its inventors Joan Daemen and Vincent Rijmen. It is used to securely encrypt and decrypt data to ensure confidentiality and integrity during transmission and storage. Let's understand the basics of the AES algorithm:

Symmetric Key Encryption:
AES is a symmetric key encryption algorithm, meaning the same key is used for both encryption and decryption. This key must be kept secret between the communicating parties to maintain the confidentiality of the data.

Key Sizes:
AES supports three key sizes: 128 bits, 192 bits, and 256 bits. These key sizes determine the number of rounds used in the encryption process and correspondingly the level of security.

Encryption Process:
The AES encryption process involves the following steps:

Key Expansion: The initial secret key is expanded to create a set of round keys. The number of rounds depends on the key size: 10 rounds for a 128-bit key, 12 rounds for a 192-bit key, and 14 rounds for a 256-bit key.

Initial Round: The input data, known as plaintext, is divided into blocks of 128 bits (16 bytes). In the first round, each byte of the plaintext is combined with the corresponding byte of the round key using a bitwise XOR operation.

Main Rounds: AES performs multiple rounds (determined by the key size) where four different transformations are applied: SubBytes, ShiftRows, MixColumns, and AddRoundKey.

SubBytes: Each byte of the block is replaced by another byte based on a substitution table (S-box).
ShiftRows: The rows of the block are cyclically shifted to the left.
MixColumns: The columns of the block are mixed to add diffusion.
AddRoundKey: Each byte of the block is combined with the corresponding byte of the round key using a bitwise XOR operation.
Final Round: The final round does not include the MixColumns transformation.

Decryption Process:
The decryption process in AES is the reverse of the encryption process. It involves the same steps as encryption, but the transformations are applied in reverse order.

Security and Performance:
AES is considered secure and has been extensively analyzed and tested. Its security is based on the strength of the encryption key, and the choice of a strong key size (e.g., 256 bits) enhances its resistance against brute-force attacks.

AES is also known for its efficiency and performance. It is optimized for both software and hardware implementations, making it suitable for a wide range of applications, including data encryption in computer systems, secure communication in networks, and data storage in cloud environments.

In conclusion, the Advanced Encryption Standard (AES) is a fundamental encryption algorithm widely used in modern cryptography and network security. Its simplicity, security, and efficiency make it a popular choice for protecting sensitive information and ensuring secure communication between parties.

Excellent bhai ! Mne nptel se course lekr galti krdi bhai, mujhe pdhai to youtube se hi krni pdrhi h ! Itna ajeeb explanation h na iit k teachers ka us NPTEL k lectures m ! Thank you very much, I've subscribed 😃

Mera dream h networking or security ki field. M bhot aagey jaaney ka

[priyanshigusain]

(thank you thank you much aapka) X1000
literally jitna thank you karu kam hai
itna simple explanation and easy to understand
mei bata nhi shakti apne meri kitni help kari hai
mere pichi baar bhi highest marks the crypto mei because of your videos
thank you so much🥰🥰❤❤

[tarachandkumawat]

Wow yarr mst explanation hai.. mene ye wala topic pure youtube par dekh liya..but aisa explanation nhi mila.. first time me hi smjh aa gya ..❤❤❤

[geek_for_life]

@Abhishek Sharma Sir, Aaj Crypto ka Paper Bahut aacha Gaya! all Questions from your Videos! Superb Playlist & Also Shared with all my Friends!

[lovetiwadiai]

you have beat everyone in concept explaining whether it is computer graphics, cryptography or any other, you are just an awesome🙇🙇🙇🙇

[amandeepkaur]

Hloo there.
I am studying in Canada but I didn't understand what my professor teach me.when I see you videos it's is very useful and I am able to understand deeply in Cryptography.
Thank you so much... 🙄

[shlokagrawal]

Thank you!!!! Watching 2 days after exam. It helped me a lot to get through my mid sems.. Love You loads sir

[Techpandey]

Brother i just say your explanation skills are next level i watch read so many thing on book but not able to get it but your 20min video explains all the things mjaaa aa gya bhai sachi thanks from all students

[TrendingBeastYT]

Book mai 1hr takk samaj nahi aya laga chor hi du yai topic but iss video mai 20 minute mai hi almost sab clear hogaya doubts . Aur baut easy laga

[namangirdhar]

You are definitely adding value to lives of upcoming engineers, you literally simplified everything. Can't get a better explanation than this.

[chauhanparikshit]

Jo chiz explain krne main Professors 15-20 classes lete hain, woh chiz aapne sirf 30 mins mein clear kar diya.
Hats off to you man!

[anandb]

Brother, i have no words to thankyou..You have xplained in such a simple manner ..Brilliant is an understatement.
