Security Key Distributed Real-time Task Scheduling Technology Research

Distributed real-time system(DRTS), especially DRTS for security-criticalapplications, there are stringent requirements for real-time and security. With theincreasing demands of safety for security-critical real-time applications such asscientific research and military applications, security has become an important designconstraint for DRTS. That how to optimize security to get better security performancein DRTS, has become an urgent problem in DRTS scheduling. Distributed real-timescheduling technology based on security-critical is an important and effective method toprotect the real-time needs as well as security needs for distributed real-time tasks. Thescheduling is to maximize the optimization get with some constraints. Therefore, how toget the maximum security during the deadline of the task is needed to be addressed inthis article.With the purpose of designing distributed real-time security-critical taskscheduling, real-time task scheduling, distributed real-time task scheduling, securityservices and security services cost models are systematically summarized and analyzedin this dissertation. Then, this dissertation lists security-critical distributed real-time taskscheduling framework, security services and the cost model for DRTS based onsecurity-critical, time analysis and modeling of the task scheduling model as well assecurity services, safety-critical distributed real-time task scheduling strategy. Finally,using the model, respectively, using the shortest path algorithm and genetic algorithm toachieve, and concludes with a series of related improvement methods and strategies.At present, the security-critical distributed real-time task scheduling is stillrelatively small, and this study of security-critical DRTS model and schedulingalgorithm is an initial research in this aspect, it may provide some contributions for thestudy of security-critical distributed real-time task scheduling.
