AES – The Advanced Encryption Standard Explained

#cryptology, #cryptography, #cryptanalysis In this video we discuss the Advanced Encryption Standard (AES) our current modern standard for symmetric encryption. AES is now older than 20 years but still very secure. All attacks found so far are only theoretical attacks. AES is the successor of the Data Encryption Standard (DES). In the video, we discuss all building blocks (AddRoundKey, SubBytes, ShiftRows, and MixColumns). MixColumns is described but the "heavy math" is omitted. The details of the Key Expansion are also not shown. In future videos, we will also discuss MixColumns math as well as the Key Expansion in detail. We also show the visualization of AES in CrypTool 2 as well as in CrypTool-online. If you are interested in implementing AES on your own, we highly recommend the following wikipedia articles: - https://en.wikipedia.org/wiki/Advanced_Encryption_Standard - https://en.wikipedia.org/wiki/Rijndael_MixColumns - https://en.wikipedia.org/wiki/AES_key_schedule You find the AES visualizations in CT-Online here: - https://www.cryptool.org/en/cto/aes-step-by-step - https://www.cryptool.org/en/cto/aes-animation If you are interested in learning the fundaments of cryptology, let me invite you to have a look at our video series about the basics of cryptology, also for beginners: https://youtu.be/jbumW7Ym03o You can download the latest version of CrypTool 2 from here: https://www.cryptool.org/en/ct2/downloads Like what I do 😄?
