AES is based on a design principle known as a substitution–permutation network, and is efficient in both software and hardware. Unlike its predecessor DES, AES does not use a Feistel network. AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. The SubBytes phase of AES involves splitting the input into bytes and passing each through a Substitution Box or S-Box.

AES uses a larger key for encryption and decryption as compare to DES. The rounds for processing of data used by AES is based on the algorithm used at a time, such as for 128 bits algorithm there are 10 rounds, for 192 bits algorithm there are 12 rounds, and for 256 bits algorithm there are 14 rounds. AES vs. DES (Background story) Before diving into AES in all of its encrypted glory, I want to discuss how AES achieved standardization and briefly talk about its predecessor DES or Data Encryption Standards. Basing their development on a prototype algorithm designed by Horst Feistel, IBM developed the initial DES algorithm in the early 1970’s. AES uses a shared key which means that the same key (or a related key) is used to encrypted the data as is used to decrypt the data. For example if I encrypted an email using AES and I sent that email to you then you and I would both need to know the shared key used to encrypt and decrypt the email.

3DES es el algoritmo que hace triple cifrado del DES; se basa en aplicarlo tres veces, con tres claves distintas, por lo que resulta mucho más seguro. AES uses substitution and permutation as a principle of encryption while DES uses a Feistel structure of encryption. AES is widely used as compared to DES since it uses modern technology that is highly responsive and secured. DES was discovered in 1977 while AES in 2001. This implies that AES uses modern technology while DES obsolete technology. 27/11/2019 · AES is de-facto world standard and is more secure than DES. DES is weak and 3DES(Triple DES) is more secure than DES. 6: Rounds: Byte substitution, Shift Row, Mix Column and Key Addition.
