AES or Advanced Encryption Standard is an encryption algorithm that was announced and approved by the United States National Institute of Standards and Technology (NIST) in November 2001.

AES replaced DES encryption algorithm and became a standard encryption technique for the US government in 2002.

AES encryption algorithm was developed by two cryptographers from Belgium, Joan Daemen and Vincent Rijmen, who submitted it to NIST where it was approved. AES, originally named Rijndael, is a family of ciphers with different key and block sizes.

AES encryption algorithm comprises of three block ciphers of 128-bits, 192-bits and 256-bits. Although encryption with AES 128-bits is quite strong and efficient, 192-bits and 256-bits key is used for higher grade of encryption.

AES is a symmetric encryption algorithm and uses a single private-key for both encryption and decryption processes. AES encryption algorithm is used by numerous organizations worldwide apart from being trusted by the US government.

AES became effective as a US federal government standard on May 26, 2002, after approval by the Secretary of Commerce. AES is also included in the ISO/IEC 18033-3 standard.

The AES is available in many different packages and specifies three key sizes: 128, 192 and 256 bits.

AES is based on a design principle known as a substitution-permutation network, a combination of both substitution and permutation, and is fast in both software and hardware.

AES is a variant of Rijndael which has a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. By contrast, the Rijndael specification per se is specified with block and key sizes that may be any multiple of 32 bits, both with a minimum of 128 and a maximum of 256 bits.


To this point in time, no practicable attacks exist against AES encryption. Therefore, AES remains a preferred encryption standard for governments, banks and other high security systems all over the world.
