Abstract(in English) Evaluation of side-channel security, i.e., resistance against side-channel attacks of cryptographic modules is definitely important. A practical issue in side-channel security evaluation for the modules with some countermeasures against attacks is the huge number of, say DPA, traces to have relevant evaluation results. Power consumption of a cryptographic module depends on its input plaintext and the key used. In order to strictly evaluate the side-channel security of the module we propose an approach in which we input chosen plaintexts to the module which are calculated from a given key to be installed into the module. We theoretically and experimentally demonstrate that this approach is very powerful. For example we need less than ten plaintexts for AES circuit which has no special countermeasures for power analysis attacks.
