Summary:
This paper analyzes the propagation of information leaked from cryptographic modules via common-mode current. We propose a simple board model in order to discuss the leakage mechanism in a general manner. Our simulation and experimental results show that the frequency characteristic of the proposed board model agrees rather well with those of a real cryptographic board. Based on these results, we propose that there needs to be a discussion on security countermeasures from the view of both EMC and side channel attack.
