SECURITY ATTACK COUNTERMEASURES

摘要

One embodiment is a method including selecting a first integer which is substantially random over the set {0, 1, 2,..., 2^s- 1} where s is a positive security integer, selecting a second integer which is substantially random over the set {0, 1, 2,..., 2^s-1}, combining the first integer, the second integer and a key, and determining a scalar multiple of the combination of the first integer, the second integer, and the key. Other embodiments include unique apparatuses, systems and methods relating to hardware fault attack countermeasures. Another embodiment includes a computer readable medium storing a program executable to randomize a CRT calculation, calculate a value which is a function of the CRT calculation, the value being a pseudo-random number if a fault has been induced in the program, the value being a predetermined value if a fault has not been induced in the program, and generate a signature which is a function of the value. Other embodiments include unique apparatuses, systems, computer accessible media, and methods relating to hardware fault attack countermeasures.
