Application background AES encryption algorithm, Encryption Standard Advanced (AES), also known as the Rijndael encryption method, is a block encryption standard used by the federal government. This standard is used to replace the original DES, has been analyzed and widely used in the world. After five years of selection process, advanced encryption standard by the National Institute of standards and Technology (NIST) was released in November 26, 2001 in the PUB FIPS 197, and in May 26, 2002 became effective standards. Key Technology The development trend of symmetric cryptography will focus on block cipher. Block cipher algorithm is composed of two parts, which is the key expansion algorithm and encryption (decryption) algorithm. The key expansion algorithm is extended to the B byte user's master key into R sub key. Encryption algorithm by a cryptography
