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.
