改进的Neumann体系结构在解决安全问题方面显示出了很好的前景。该体系结构通过单独的系统总线将网络通信组件与计算机系统的其他部分分开。两个系统总线之间的数据交换只能通过总线控制器通过计算机操作员发出的命令进行。安全的微操作系统用于保证通信的完整性。在微处理器上运行的微操作系统位于“红色”区域。它使用在启动过程中自动加载到微处理器内存的固件映像。看门狗监控系统,并在达到预设阈值时重置系统。此外,内存保护和虚拟化技术用于增强运行时安全性和防止代码注入。
Modified Neumann architecture has shown promising in solving security problems. The architecture separates the network communication component from the other parts of computer system with a separate system bus. Data exchange between the two system buses can only be performed through the Bus Controller via a command issued by the computer operator. A secured micro-operating system is used to guarantee the integrity of communications. The micro-OS that runs on a microprocessor resides in the "red" zone. It uses a firmware image that automatically loads to the microprocessor memory during booting process. A watch-dog monitors the system and reset the system whenever a preset threshold is met. In addition, memory protection and virtualization techniques are used to enhance runtime security and prevent code injection.
