An output-decision-based negative feedback control method and system. The method includes: receiving, by an output decider, output responses of at least two heterogeneous functional equivalents, and dividing numbers corresponding to the at least two heterogeneous functional equivalents into at least one set according to the output responses; determining, by the output decider, credibility of each set according to the output responses, and sending the at least one set and the credibility corresponding to each set to a feedback controller via decision information; generating, by the feedback controller, a first scheduling policy and/or a second scheduling policy according to the decision information; and sending, by the feedback controller, the first scheduling policy to an input proxy, and/or sending a change instruction to the heterogeneous functional equivalent indicated by the second scheduling policy. The method can prevent in advance and process a heterogeneous functional equivalent that may be faulty.

Output-decision-based negative feedback control method and system

An apparatus for generating heterogeneous functional equivalent and method thereof includes: a heterogeneous functional equivalent generator and an element pool connected to the heterogeneous functional equivalent generator, where the element pool includes at least one element. The heterogeneous functional equivalent generator is configured to obtain a generation policy and is further configured to select element sets corresponding to the number from the element pool according to the generation policy. The heterogeneous functional equivalent generator is further configured to generate the number of heterogeneous functional equivalents based on the selected element sets. Because the elements for constructing heterogeneous functional equivalents are different, the relationship between element and service response output by the heterogeneous functional equivalent to outside is uncertain, thereby making it uneasy to sniff an unknown defect or a backdoor of the heterogeneous functional equivalent, and lowering the success rate of an intruder's attack on the heterogeneous functional equivalent.

Apparatus for generating heterogeneous functional equivalent and method thereof

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.
