Why is it important?

Side-channel attack is a practical threat to cryptosystems. When the designers design an application specific IC chip with crypto module, they try to mitigate the vulnerability against side-channel attacks. However, it is difficult for designers to estimate the vulnerability at design stage without simulation based side-channel leakage analysis techniques. In this paper, we proposed simulation technique which is optimized for evaluationg side-channel leakage of very large-scale integration.


We proposed simulation-based power and EM side-channel leakage analysis techniques. In this paper, the proposed simulation flow is verified for the correctness and accuracy of side-channel leakage through detailed comparisons with silicon measurements. The design flow of an IC chip can equip the proposed techniques for the exploration of side-channel attack resiliency. It helps designer to implement crypto modules to hardware with high resiliency against side-channel attack.
