What is the Advanced Encryption Standard (AES)?

Definition and meaning of Advanced Encryption Standard

The Advanced Encryption Standard (AES) is a symMetric-key Block Cipher set of rules and U.S. Authorities popular for sTable and labeled statistics encryption and Decryption.

In December 2001, the National Institute of Standards (NIST) approved the AES as Federal Information Processing Standards Publication (FIPS PUB) 197, which specifies utility of the Rijndael Algorithm to all touchy labeled inFormation.

The Advanced Encryption Standard became in the beginning referred to as Rijndael.

What Does Advanced Encryption Standard Mean?

The AES has three fixed 128-Bit Block Ciphers with Cryptographic Key sizes of 128, 192 and 256 bits. Key Length is limitless, whereas the bLock length most is 256 bits. The AES layout is based totally on a substitution-permutation commUnity (SPN) and does no longer use the Data Encryption Standard (DES) Feistel Network.

In 1997, the NIST iNitiated a five-year algorithm improvement manner to UPDATE the DES and Triple DES. The NIST set of rules selection sySTEM facilitated open Collaboration and verbal excHange and blanketed a near evaLuation of 15 applicants. After an severe evaluation, the Rijndael design, created with the aid of Belgian cryptographers, turned into the very last choice.

The AES changed the DES with new and updated capabilities:

• Block encryption Implementation
• 128-bit organization encryption with 128, 192 and 256-bit key lengths
• Symmetric algorithm requiring only one encryption and decryption key
• Data Protection for 20-30 years
• Worldwide Access
• No royalties
• Easy overall implementation

What does AES stand for?

When we refer to AES as an acronym of Advanced Encryption Standard, we mean that AES is formed by taking the initial letters of each significant word in Advanced Encryption Standard. This process condenses the original phrase into a shorter, more manageable form while retaining its essential meaning. According to this definition, AES stands for Advanced Encryption Standard.
