Critical systems are systems that are not permitted to fail during its operation schedule, this trailed that all its constituent embedded systems (nodes) must be optimized to an appreciable degree of reliable functionality. The requirement constraints of embedded systems application design make software-defect masquerading faults inevitable as the nodes collaboratively relate to ensure a dependable service delivery of the critical systems. This is because embedded systems networks are closed network and therefore masquerading faults only emanates from defects in the software of the nodes. To remedy this attack that threats seriously the critical systems reliability and dependability, an algorithm was proposed. The proposed solution involves three main stages:the pre-authentication stage, authentication stage and the auto-repair stage. This work included the last stage so as to ensure the system auto-repairability from fault state. The network simulation of the proposed solution was conducted. The Simulation results showed that the proposed solution effectively detect and prevent masquerading faults.

Abstract


Critical systems are systems that are not permitted to fail during its operation schedule, this trailed that all its constituent embedded systems (nodes) must be optimized to an appreciable degree of reliable functionality. The requirement constraints of embedded systems application design make software-defect masquerading faults inevitable as the nodes collaboratively relate to ensure a dependable service delivery of the critical systems. This is because embedded systems networks are closed network and therefore masquerading faults only emanates from defects in the software of the nodes. To remedy this attack that threats seriously the critical systems reliability and dependability, an algorithm was proposed. The proposed solution involves three main stages:the pre-authentication stage, authentication stage and the auto-repair stage. This work included the last stage so as to ensure the system auto-repairability from fault state. The network simulation of the proposed solution was conducted. The Simulation results showed that the proposed solution effectively detect and prevent masquerading faults.
