Formal modeling and verification method for inter-process communication mechanism of microkernel operating system based on Event-B method

The invention discloses a formal modeling and verification method for an inter-process communication mechanism of a microkernel operating system based on an Event-B method. The method comprises the steps that demand design analysis is conducted, specifically, according to a microkernel operating system inter-process communication mechanism based on an Event-B method, in combination with a subscriber publisher mode, design analysis is conducted to meet the original demand of Event-B modeling; according to the inter-process communication mechanism of the microkernel operating system based on theEvent-B method and the result of the original demand, designing and analyzing meet the rewriting demand of Event-B modeling; and modeling and refining verification: a model for verifying the inter-process communication mechanism of the microkernel operating system is designed and created based on the Event-B method according to a rewriting demand. Proving obligations needing to be verified by themodel comprise a model fu
