A masking based RSA to resist power analysis attacks

摘要

In this paper we have presented a detail on masking which is a technique used to resist power analysis attacks. Some of the works that have been done using this technique have been analyzed. Also, a masking based approach for RSA has been proposed. The proposed works first masks the plaintext and then execute the RSA instructions. In between, some real time random instructions were also inserted which not only masked the values but also could provide variations in the power consumptions thus resisting power analysis attacks.
