  • Fault detection in exponentiation and point multiplication operations using a montgomery ladder
    Patent number: 8442216
    Abstract: A system and method are provided enabling implicit redundancies such as constant differences and points that should be on the same curve, to be checked at the beginning, end and intermittently throughout the computation to thwart fault injection attacks. This can be implemented by checking the constant difference in point pairs during point multiplication, by checking constant scalings in exponentiation pairs, and by checking that any intermediate point is on the curve and/or in the correct subgroup of the curve.
    Type: Grant
