In the paper on the basis of the IDEA16-8 network were developed networks RFWKIDEA16-8, RFWKIDEA16-4, RFWKIDEA16-2 and RFWKIDEA16-1 that consist of eight, four, two and one round function. The main advantage of the proposed networks is that during encryption and decryption using the same algorithm as well as a round function can be used any cryptographic transformations. In the developed networks algebraic operations are variable, as these operations can be used the operations of addition and multiplication in modulo & XOR. Lengths of subblocks in these networks are 8, 16 and 32 bits. Besides using proposed in paper networks can be created encryption algorithm with lengths of block 128, 256 and 512 bits.References
