METHOD FOR INCREASING SECURITY IN A DISTRIBUTED REAL TIME SYSTEM, AND REAL TIME SYSTEM

摘要

The invention relates to a method for increasing security in a distributed real‑time system, comprising a multiplicity of computer nodes and distributing units, wherein at least one incremental scheduler can dynamically plan deterministic time‑controlled channels between the computer nodes. At least one trusted Certification and Monitoring Authority (CMA) stipulates the maximum share of the bandwidth of each distributor unit that a scheduler is permitted to plan, wherein these stipulations are communicated to the distributor units and the schedulers by the CMA by means of messages, and wherein a distributor unit that receives from a scheduler a schedule that takes up more bandwidth than this maximum share rejects this schedule. In addition, the invention relates to a computer system for carrying out such a method.
