Abstract
According to an embodiment, a generating device includes a first key generator, a second key generator, and an output unit. The first key generator is configured to generate a first key according to a first key rule in which the first key is generated from a random number, the first key being a bit sequence. The second key generator is configured to generate a plurality of second keys according to a second key rule in which the second keys are generated from the first key, the second keys being bit sequences partly correlated to one another. The output unit is configured to output the first key and at least one of the second keys.
