A structural encoding unit and an error correction decoding unit are divided. The structure encoding unit is divided into input branch processor and an input proxy processor; and the error correction decoding unit is divided into an output routing processor, an output proxy processor, an adjudication branch processor, an adjudication proxy processor and a voting processor. The input branch processor is used for duplicating and distributing messages, the arbitration branch processor is used for duplicating and distributing data, the voting processor is used for performing voting, and the output routing processor is used for selecting an output result from processing results of the output proxy processor according to a voting result of the voting processor.

Input/output system applied to network security defense system

A method for automatically sensing attack behaviors, the method including: distributing a service request from a network switch to a response module, where the response module includes a main controller configured for data interaction processing and an auxiliary controller configured for interactive data processing; generating, by the main controller and the auxiliary controller in the response module, respective response data according to the service request, respectively; and comparing the respective response data of the main controller with the respective response data of the auxiliary controller; if a result of comparison is inconsistent, indicating the network switch is abnormal, an administrator is informed, and the response data generated by the auxiliary controller is fed back to the network switch; and, if the result of comparison is consistent, the response data generated by the main controller is fed back to the network switch.

Method, device and ethernet switch for automatically sensing attack behaviors

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.
