抄録

Iwamoto et al. proposed the strong security definition for ramp secret sharing schemes with general access structures, and also proposed an integer optimization approach to construct a secret sharing with the smallest share size and general access structure, based on a threshold secret sharing scheme. This note proves that if the underlying threshold scheme is strongly secure then the constructed multiple assignment scheme gives a strongly secure secret sharing scheme.
