In side channel attacks, the secret keys are obtained from physical data in the implementation of the cryptosystem. For example, information of the CRT-RSA secret keys can be extracted from exponentiation in the decryption algorithm.
However, if accuracy of the physical data is not high, the secret keys are not obtained easily. In this paper, we propose the way of recovering the CRT-RSA secret keys from the error keys extracted from exponentiation based on $2^{m}$-ary method. Moreover, we analyze our algorithm and verify the effectiveness of our algorithm by numerical experiments. |
