Masters Student Presentation:
Features of Advanced Encryption Standard
Venkata Marella
In cryptography, the Advanced Encryption Standard (AES) is an
encryption standard adopted by the U.S. government. The standard
comprises three block ciphers, AES-128, AES-192 and AES-256, adopted
from a larger collection originally published as Rijndael. Each AES
cipher has a 128 bit block size, with key sizes of 128, 192 and 256
bits, respectively. The AES ciphers have been analyzed extensively and
are now used worldwide, as was the case with its predecessor, the Data
Encryption Standard (DES). It is available in many different
encryption packages. AES is the first publicly accessible and open
cipher approved by the NSA for top secret information In the
presentation we will be talking about the evolution of AES, features
of the AES, working of the AES, security of the AES and finally
compare AES with DES.
