摘要： 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.

摘要： 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.

摘要： Provided are a security defense method and apparatus applied to a network security defense system. The method includes: using memoryless technology in a cyberspace information system, where the memoryless technology includes technology which is not affected by generalized disturbance; eliminating a memory of the cyberspace information system on an effect of random disturbance by using a redundancy and replacement mechanism; and eliminating a memory of the cyberspace information system on an effect of non-random disturbance by eliminating a memory of a program running in the cyberspace information system and/or data in the cyberspace information system. The present solution can block a memory of the cyberspace information system on an error caused by the generalized disturbance including the non-random disturbance and the random disturbance, thereby improving security of the cyberspace information system.
