Advanced Encryption Standard
Advanced Encryption Standard中文称为AES加密标准。本文件实现AES-128算法,并且容易扩展到192, 256 bit。 The irreducible polynomial of GF(2^8) is m(x) = x^8 + x^4 + x^3 + x + 1 const int Nr = 10; round number const int Nk = 4; the seed has Nk words AES-128 Nr=10, Nk = 4 AES-192 Nr=12, Nk = 6 AES-256 Nr=14, Nk = 8
