Provably secure higher-order masking of aes
WebbMasking is a well-known countermeasure to protect block cipher implementations against side-channel attacks. The principle is to randomly split every sensitive intermediate variable occurring in the computation into d + 1 shares, where d is called the masking order and plays the role of a security parameter. Although widely used in practice, masking is often … WebbThis paper presents a practical smart card implementation of advanced encryption standard AES-128 algorithm combined with a simple yet effective masking scheme to protect it against first-order power analysis attacks in both time and frequency domain. ...
