Software/Hardware Device with Uncertain Service Function and Structural Characterization, and Scheduling Method for Thereof

摘要

The present invention discloses a software/hardware device with uncertain service function and structural characterization and a method for scheduling the same. The device comprises a policy generator, a scheduler and a plurality of heterogeneous functional equivalents with equivalent functions, wherein, the policy generator is configured for providing a scheduling policy for the heterogeneous functional equivalents to the scheduler; the scheduler is configured for receiving an external service request, determining heterogeneous functional equivalents that provide a service to the external service request according to the scheduling policy given by the policy generator, assigning the service request to the determined heterogeneous functional equivalents, and outputting a service response which has an uncertain relation with uncertain structural characterization according to a feedback and the scheduling policy given by the policy generator. Therefore, the service response provided to the service request has an uncertain correspondence relation with feedback results of the heterogeneous functional equivalents of the device, so that the effectiveness of detection or attack on an unknown loophole, trapdoor of the device is greatly lowered, and the protective ability of the software/hardware device is enhanced.
