Why is the M480 AES sample output different from the network tool? http://testprotect.com/appendix/AEScalc 日付:2018-11-27
In the case of a network tool:
Key: 000102030405060708090a0b0c0d0e0f
Plaintext: 00112233445566778899aabbccddeeff
Ciphertext: 69c4e0d86a7b0430d8cdb78070b4c55a
The key input corresponding to the AES register:
CRYPTO_AESn_KEY0 = 0x00010203
CRYPTO_AESn_KEY1 = 0x04050607
CRYPTO_AESn_KEY2 = 0x08090a0b
CRYPTO_AESn_KEY3 = 0x0c0d0e0f
Input data:
CRYPTO_AES_DATIN = { 0x00112233, 0x44556677, 0x8899aabb, 0xccddeeff }
The obtained output data:
CRYPTO_AES_DATOUT = { 0x69c4e0d8, 0x6a7b0430, 0x d8cdb780, 0x70b4c55a }
It should be noted that the data processing of AES is handled by the variable type of WORD. There are different LSBs and MSBs from the variable type of BYTE.
