In this paper, we propose a new block cipher called BC2 (Block Cipher 2). We make a cipher using components that are believed secure. The structure of BC2 is very simple. We use Feistel network with input-output 128 bits, matrix Maximum Distance Separable (MDS) 8x8 with branch number 9 to give high diffusion, a function affine equivalent to the inverse function in GF(2 8 ) that we get from Camellia and Hierocrypt S-Box for confusion and we make FN function, based on FL function of Camellia. We
