AES Rijndael is a block cipher developed by NIST as the Advanced Encryption Standard (AES) replacing DES and published as FIPS 197 in November 2001 to address the threatened key size of Data Encryption Standard (DES). AES-Rijndael was developed by the researchers, Rijndael and was selected from five finalists. Advancement in computation speed every day puts lots of pressure on AES and AES may not with stand attack for longer time. This paper focuses on improving security of an encryption algorithm, beyond AES.
