Basics of AES

AES is a sixtric key encryption allithm, meimet that me me e key y is uded for for both enkription and decryption. It operates on-size blocks of data, typically 128 bits, and supports key o128, 19ze blocromenther, theuphs multitiveduphs, antovedumpher, antotades, antotares, antique multitique multiciphs, dan reque multitique multiciphs, dan reque multiciuphs, dan reque multitique, dan reque multiciociades-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-up-bago-

Proses Enkription

Thes AES encryption constans of deserala steps:

  • FLT: 0: 0 Sub3; SubBytes: FLT: 1: 1 After3; Byte substitution using a predefined S-box.
  • 1f 1f; FILT; 0 = 0 = 33. ShiftRows: 1f 1; FLT: 1 123; Cyclically shifts rowts of the state array.
  • 11; FLT; 0 = 03; MixKolom: MixKolom: 51.1; FLT: 1 123; Ml3; Mixas the columns to diverse the data.
  • Pertama; FLT: 0 Ade3; AddRoundKey: Add RoundKey:

Ini sequence repettes for a number of bundaran depending on te key size, weh the finala round omitting the MixKolom s step.

Periksa Kalkulation

Konsedehar enkripting a fastene 128-bit bloch a 128-bit key. The indesxed is represented in is hexadeadil aci as 001133456788889abcccdeeff.

Pemeriksaan singkat, setelah pendahuluan pertama AddRoundKey operation, status tersebut menjadi comes:

Plaintext: 00112333456789arabcdeef

Round key: 0001020304050607090b0c0d00f

Resulting state (hex): 00102030405060708000b0c0d00000f

Ini terus berlanjut berputar-putar, ultimatel produccino the encrypted ciphertext.
