Abstract: 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.

Abstract: An apparatus, method, and device for encapsulating heterogeneous functional equivalents are disclosed. The apparatus includes a redundancy controller, an input proxy, and an output proxy. In this application, a plurality of heterogeneous functional equivalents are encapsulated by an input proxy and an output proxy, so that the apparatus can support adaptation, normalization and dis-cooperation to cut a communication link employed by an attacker, such that it is difficult for the attacker to sniff and exploit unknown defects or backdoors, and a success rate of the attacker attacking an information system is reduced.

Abstract: An example topology construction method for satisfying partition tolerance, comprising: combining the consortium blockchain consensus mechanism with the network topology structure to make the consortium blockchain consensus satisfy the partition tolerance in probability; abstracting the partition tolerance of a system into a class of convergent Markov process and computing a steady-state probability of the system; estimating the probability and the average minimum repair time of failing to meet consistency or availability in the event of a partition failure with a given number of failure channels, and a partition tolerance probability and an average minimum repair time of the system are obtained; and analyzing the resource overhead and the partition tolerance under different network topologies according to the obtained partition tolerance probability and the average minimum repair time, and constructing the network topology structure with suitable scale and high partition tolerance for the consortium blockcha

Abstract: 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.
