   AES: How to Design Secure Encryption

   In 1997, Rijndael was selected as the Advanced Encryption Standard (AES) by the US National Institute of Standards and Technology. AES is widely used today in various applications including hard drive encryption and internet communication. At its core, AES operates as a block cipher using concepts of confusion and diffusion to ensure security. The process involves multiple rounds of byte substitution, row shifting, column mixing, and key addition, making it a robust encryption standard.
