AES Example | AES Encryption Example | AES solved Example | Solved Example of AES encryption | AES Transformation Function Follow my blog: https://www.chiragbhalodia.com/2021/09/aes-algorithm.html In this video, I have explained introduction of AES. Then explained all transformation fuctions of AES with example (Example from William Stallings book) is in this video. Watch carefully. AES Solved example. Introduction of AES: AES uses 128 bits of plain text. AES consists of multiple rounds of processing different key bits like, 128 bits key – perform 10 rounds of encryption 192 bits key – perform 12 rounds of encryption. 256 bits key – perform 14 rounds of encryption. For encryption, each round consists of the following four steps: Sub Bytes, Shift Rows, Mix Columns, Add Round Key. Above steps also called AES transformation function. AES Sub BytesTransformation Function: First transformation function of AES is called as Substitute Bytes (Sub Bytes). It is also known as forward substitute bytes transformation. AES defines a 16 x 16 matrix of byte values, called an S-box, that contains a permutation of all possible 256 8-bit values. These row and column values serve as indexes into the S-box to select a unique 8-bit output value. AES Shift Rows Transformation Function: Second transformation function of AES is called as Shift Rows. It is also called as forward shift row transformation. Rules of shifting rows are as below, Row 1 ⇒ No Shifting Row 2 ⇒ 1 byte circular left shift Row 3 ⇒ 2 bytes circular left shift Row 4 ⇒ 3 bytes circular left shift AES Mix Column Transformation Function: Third transformation function of AES is called as Mix Columns, operates on each column individually. Each byte of a column is mapped into a new value that is a function of all four bytes in that column. Here in this function State Array is Output of Shift Rows function. AES Add Round Key Transformation Function: Fourth transformation function of AES is called as Add Round Key. It is also known as forward add round key transformation. The 128 bits of State are bitwise XORed with the 128 bits of the round key. Add Round Key proceeds one column at a time. 0:00 Introduction 0:15 Outline 0:45 Introdcution of AES 2:13 AES Sub Bytes (Explain with example) 5:47 AES Shift Rows (Explain with example) 8:50 AES Mix Column (Explain with example) 32:27 AES Add Round Key (Explain with example) If you like my video contents, please LIKE, COMMENT, SUBSCRIBE & SHARE with your friends. -------------------------------------------------------------------------------------------------------------- Check out other video on my channel Block Cipher and Stream Cipher: https://youtu.be/-gQrm5j0RkQ Confusion & Diffusion (Frustrated Statistical Analysis or Claud Shannon Properties): https://youtu.be/PJrW6ZqQipo Feistel Cipher Structure (to understand DES): https://youtu.be/emJ0p6h48u4 Data Encryption Standard (DES) Algorithm: https://youtu.be/cVhlCzmb-v0 DES Example using Animation: https://youtu.be/3YBwhWuXZ0o Strength & Weakness of DES, Avalanche effect in DES: https://youtu.be/Xy1hver_aaw Advanced Encryption Standard (AES) Algorithm with structure: https://youtu.be/X8whYEWoDSI AES Example using Animation: https://youtu.be/ZPLEtxxjCYA Key expansion in AES: https://youtu.be/14SAn4IEAHk -------------------------------------------------------------------------------------------------------------- You can always connect with me at: Follow my blog: https://www.chiragbhalodia.com Like my Facebook page: https://www.facebook.com/chiragbhalodia25 Follow me on Instagram: https://www.instagram.com/chiragbhalodia.25 Follow me on twitter: https://twitter.com/chiragsbhalodia Join telegram group: https://t.me/chiragbhalodia Subscribe me on youtube: https://www.youtube.com/c/ChiragBhalodia Follow me on Quora: https://www.quora.com/profile/Chirag-Bhalodia-2 -------------------------------------------------------------------------------------------------------------- Playlist available on my channel: Network Security (CNS, INS, IS): https://youtube.com/playlist?list=PLzQqHxFtQGyfiYWaDnasLdy1JPK3JS06o Computer Network (CN) with animation: https://youtube.com/playlist?list=PLzQqHxFtQGycfs9Vn8BYy0ic0wh-oL9UC VFX Animation & Fun Videos: https://youtube.com/playlist?list=PLzQqHxFtQGyd9esvf-t5XYOKhxQS0tDWx Comupter Organization & Architecture (COA, CA, CO): https://youtube.com/playlist?list=PLzQqHxFtQGyd-uDzS9vov8hJfm03X_SzC Assembly Language Programming: https://youtube.com/playlist?list=PLzQqHxFtQGyeTa82xQyceYxaf-iyZBICw Computer Graphics: https://youtube.com/playlist?list=PLzQqHxFtQGycg_TJBA6uFGDLwbotjs68h #chirag_bhalodia #chiragbhalodia #networksecurity #cryptography #AES_Solved_Example #How_to_solve_aes_example Keep learning, keep supporting 🤝✨💯
