Side channel risk qualitative evaluation model based on hierarchy
Yao Jianbo, Tao Zhang · Computer Engineering and Applications Journal · 2012
As the side channel attacks diversification,the crypto-chip safety risk assessment and select optimal attack and defense tactics become the present study blind spot on many side channel leak conditions.In view of many side channel leaks,from the side channel information leak angle,using the information entropy to quantitative side channel information of the crypto-chip,mutual information as safety risk measure,a hierarchy-based risk evaluation model is presented.This model uses bottom-up,first local then the whole analysis method,divides the different of side channel leak and attack,and uses mutual information as the quantitative indexes of side channel leaks risk,evaluates safety risk effectively through the fuzzy comprehensive analysis method.
