1. RSA AES
1.RSA is an asymmetric (or public key)
cryptography algorithm
1.AES is a symmetric cryptography
algorithm
2.Encryption and decryption is done
with a separate keys(public and private
keys) isnRSA
2. Encryption and decryption is done
with a single key in AES
3.The strength of a 2600-bits RSA key 3. The strength of a 128-bitAES key
4.Created by :Ron Rivest,AdiShamir,
and Leonard Adleman in 1978
4. Created by :Vincent Rijmen,Joan
Daemen in 2001
5.Ciper Type :Asymmetric Block cipher 5. Ciper Type : Symmetric Block Ciper
6.LeastSecure 6.Excellent Security
7. RSA is slower than AES 7.AES ismust fasterthanRSA
8. RSA uses a variable sizeencryption
block and a variablesize key
8. AES uses several rounds in which
each round is made of severalstages
9. Block Size : Variable 9. Block Size :128 bits
