1. A digest value calculating device comprising:
circuitry configured to:
determine a value of a common parameter used in common for each of a plurality of paths respectively associated with Modes;
calculate, for each of the plurality of paths, a digest value corresponding to the path on a basis of the value of the common parameter and a name of the path;
associate the digest value corresponding to the path and an Mode corresponding to the path with each other;
determine a value of a first common parameter and a value of a second common parameter;
calculate a value of an internal state on a basis of a part of the name of the path and the value of the first common parameter; and
recalculate the digest value on a basis of the value of the internal state, a remainder of the name of the path, and the value of the second common parameter.
