Abstract
The secure computation apparatus includes: a former half window frame column generation unit configured to generate, with respect to a vector subVector ({g}, s+1, i} obtained by extracting elements from an (s+1)-th element to an i-th element of {g}, a bit column obtained by an OR operation performed on all bits from the end to each position as a former half window frame flag column {w}; a latter half window frame column generation unit configured to generate, with respect to a vector subVector ({g}, i+1, t} obtained by extracting elements from an (i+1)-th element to a t-th element of {g}, a bit column obtained by calculating OR of all bits from the head to each position as a latter half window frame flag column {w}; and a window frame flag column generation unit configured to generate a window frame flag column {w} by combining the former half window frame flag column {w} from the front side and the latter half window frame flag column {w} from the rear side having {0} interposed therebetween.
