Advanced Encryption Standard (AES) Algorithm

The more popular and widely adopted symmetric encrypt algorithm likely to be encountered nowadays is the Advanced Encryption Standard (AES). It is found at least six time faster than triple DES.

A replacement for DES was needed as its key size was too small. With increasing computing power, it was considered vulnerable against exhaustive key search attack. Triple DES was designed to overcome this drawback but it was found slow.

The Advanced Encryption Standard (AES), also known by its original name Rijndael, is a specification for the encrypt of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. AES is a subset of the Rijndael cipher developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of ciphers with different key and block sizes.

The features of AES are as follows:
  • Symmetric key symmetric block cipher
  • 128-bit data, 128/192/256-bit keys
  • Stronger and faster than Triple-DES
  • Provide full specification and design details
  • Software implementable in C and Java
Example ::
import securefile.aes_algorithm as aes_algo
