摘要:
A system comprises reception of input data of a Galois field GF(2k), mapping of the input data to a composite Galois field GF(2nm), where k=nm, inputting of the mapped input data to an Advanced Encryption Standard round function, performance of two or more iterations of the Advanced Encryption Standard round function in the composite Galois field GF(2nm), reception of output data of a last of the two or more iterations of the Advanced Encryption Standard round function, and mapping of the output data to the Galois field GF(2k).
