Abstract

An encryption evaluation support system, includes an evaluation executing unit, and a point storing unit. The evaluation executing unit receives a figure representation of an encryption algorithm.
The figure representation includes a plurality of unit figures. The point storing unit stores points allocated to the plurality of unit figures respectively. The evaluation executing unit gives the points to the plurality of unit figures of the figure representation, respectively, to output the points given to the plurality of unit figures of the figure representation.
