一种嵌入式防火墙安全保护创新机制

传统的防火墙通常是在内部网络与外部网络之间实现保护机制,通过对输入和输出网络的数据包进行实时监测,一旦发现安全威胁便会立刻做出防护响应,具有数据处理时间短、效率高等特点,能够满足大多数操作程序的应用,但是也存在成本高、实现难等弊端.论文针对以上问题,提出了一套基于AMR处理器的嵌入式防火墙安全保护创新机制,给出了嵌入式防火墙的总体框架及软硬件架构设计,选用了性能良好的S3C2410X嵌入式芯片,对嵌入式防火墙的网卡驱动、应用程序的关键技术进行详细研究,对基于AMR处理器的嵌入式防火墙的通信性能进行了对比测试,其通信速率可达15.5Mpbs左右,比一般的处理器通信性能提高2.15倍.

An Embedded Firewall Innovative Mechanism

Traditional firewall between the internal network and external network protection mechanisms,real-time monitoring of input and output network packet,once discovered security threats will immediately make a protective response time data processing,high efficiency characteristics,can meet most of the operating procedures of application,but there are also high cost,difficult and other defects.To solve the above problem,an AMR processor-based embedded firewall security protection innovation mechanism gives the Embedded Firewall overall framework and the hardware and software architecture design,the choice of a good performance the S3C2410X embedded chips,embedded the firewall NIC driver,application of key technologies for detailed study,the and simulation comparison test of the communication performance of the AMR processor-based embedded firewall,the communication rate up to 15.5Mpbs about 2.15 to improve communication performance than the processor times.
