Abstract
Provided is a secure computation technique for efficiently uniforming exponent parts of floating points. A secret exponent part uniforming system which, from a share ([[a]], [[ρ]]) of a floating point vector (a=(a, . . . , a),ρ=(ρ, . . . , ρ)), calculates a share ([[b]], [[ρ]]) of a floating point vector with uniformed exponent parts (b=(b, . . . , b),ρ=(ρ, . . . , ρ) (ρ=max{ρ, . . . , ρ}), 2a≈2bis satisfied), comprises a mantissa part calculation means for calculating a share [[b]]by calculating a share [[b]](b=2a) of the number bfrom the i-th element of the share [[a]]and the i-th element of a share <<ρ>>converted by replicated secret sharing from a share [[ρ]]=[[ρ]]−[[ρ]].
