1. A device for managing quality of shared random numbers generated between a first communication device and a second communication device, comprising:
a memory that stores a set of instructions for synthetic judgment of randomness test results; and
a processor configured to execute instructions to:
perform the synthetic judgment for the shared random numbers by combining a result of a first randomness test and a result of a second randomness test, the first randomness test being performed on the shared random numbers by the first communication device, and the second randomness test being performed on the shared random numbers by the second communication device; and
notify a result of the synthetic judgment to at least one of the first communication device and the second communication device,
wherein the first randomness test and the second randomness test are different with respect to at least one of randomness test method and random number portion.
