Correlation power attack on AES cipher chip with rotating masking
摘要
Abstract
Aiming at the AES cipher chip with rotating S‐boxes masking ,a new method of correlation power attack was proposed .Firstly ,a variance analysis approach was used to identify the time in‐stances when the plaintext blinding and the relevant S‐box were computed .Secondly ,the random off‐set of each trace was guessed by calculating the correlation coefficients between hamming weight and the points of masking operation .Lastly ,the secret key was revealed by operating correlation power attack using the guessed hamming distance between S‐box input and output .Experimental results from attacking 1 × 104 traces randomly selected in DPA Contest V 4 dataset w hich is publicly available show that this method requires only 45 traces to recovery the key correctly .关键词
