Bypass Leakage Risk Assessment Based on Mutual Information Game

Mutual information game theory is introduced in the decision-making process of the cryptographic chips designers (defense party) and the attacker, a risk quantification evaluation model based on mutual information game is built. It investigates the attack and designs tactics choice to security risks, and combining with the quantitative methods of the mutual information, gives the optimization tactics selection method of the bothsides of attack and designs on Nash equilibrium conditions, gives the mutual information benefits of the both sides of attack and designs on Nash equilibrium. Through the case analysis, the validity of the strategy is proved.
