基于互信息博弈的侧信道攻击风险评估模型

将互信息博弈理论引入密码芯片设计者(防御方)和攻击者的决策过程，建立一种互信息博弈的风险量化评估模型。考察攻防策略的选择对安全风险的影响，并结合互信息的量化方法，给出Nash均衡条件下攻防双方的优化策略选择方法及互信息收益。通过案例分析，验证了该策略的有效性。

Side Channel Attack Risk Evaluation Model 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 both sides 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.
