Transcript of "Aes (advance encryption standard) "

  1. 1. Directed by: Sina Manavi
  2. 2. What is AES?AES features:AES vs. DESAES vs. RSASummaryQ&A
  3. 3.  After Des Cracked, Triple-DES which was slow they announced in competition for calling algorithms and between 15 algorithms on October 2000 Rijndeal which was invented by two Belgians, Joan Daemen, Vincent Rijmen. On 2002 Rijndael became AES. Rijndael is free in commercial and non-commercial use
  4. 4.  designed simple Low memory cost High speed algorithm The key used to decrypt and encrypt is same Cipher text and plain text are same size Fast both in Software and Hardware
  5. 5. AES is a Symmetric block cipher algorithm ,a supersedes of DES.This cipher is good for encoding and decoding files, documents,and etc. Reliability and high performance made it distinctbetween other methods. On the other hand if you wish to useAES in communication, because of the Key exchange problemthis problem is solved by using a asymmetric algorithm such asRSA. Message is encoded by a private key and the receiverdecode it with the public key. Although asymmetric algorithmsare slow, we can use them for exchanging the key and encodethe data with symmetric algorithm,
  6. 6.  DES is really old while AES is relatively new DES is breakable while AES is still unbreakable DES uses a much smaller key size compared to AES DES uses a smaller block size compared to AES DES uses a balanced Feistel structure while AES uses substitution-permutation
