An Improved Timing Attack With Error Detection on RSA-CRT

Several types of timing attacks have been published, but they are either in theory or hard to be taken into practice. In order to improve the feasibility of attack, this paper proposes an advance timing attack scheme on RSA-CRT with T-test. Similar timing attacks have been presented, such as BB-Attack and Shindler's attack, however none of them applied statistical tool in their methods with such efficiency, and showed the complete recovery in practice by attacking on RSA-CRT. With T-test, the authors enlarge the 0-1 gap, reduce the neighborhood size and improve the precision of decision.
