Abstract
In a method of managing a plurality of cached keys, a determination is made as to whether to generate an additional key for the plurality of cached keys. If it is determined to generate the additional key, control of a central processing unit is acquired and a first current time is recorded. While a difference between a second current time and the first current time is not greater than a predefined time slice, one or more operational units of a plurality of operational units for generating the additional key are executed on the central processing unit. If the additional key is completed, the additional key is saved as a cached key with the plurality of cached keys.
