Abstract(in English) | The composing method of S-BOX in AES using composite fields is effective to implement compact cryptosystem, since the circuit scale can be greatly reduced. Recently, since it has become important for cryptosystem to apply tamper resistance, several methods to consist inversion operation circuit with random masked logic at module level have been proposed for DPA countermeasures. On the other hand, RSL (Random Switching Logic) gate that masks internal variables with random value at the primitive gate level had been also proposed. In this research, we propose MRSL (Modified RSL) to improve RSL. Moreover, implementation of a S-BOX circuit composed with MRSL on FPGA (Virtex1000), and its evaluation of DPA countermeasure ability is also shown. |
