Today one of the most effective symmetric block ciphers is AES. In the paper block encryption algorithms AES-IDEA32-4 and AES-RFWKIDEA32-4 on the basis of networks IDEA32-4 and RFWKIDEA32-4 were developed. In the encryption algorithm AES-IDEA32-4 as a round function were selected transformation SubBytes(), ShiftRows(), MixColumns(), AddRoundKey(), and in the encryption algorithm AES-RFWKIDEA32-4 as a round function were selected transformation SubBytes(), ShiftRows(), MixColumns(). The block length of encryption algorithm is 512 bits, the number of rounds is 10, 12, 14 and key length changes from 256 bits to 1024 bits with a step of 128 bits.
