基于ISO26262的以太网网关硬件开发研究

Design of Hardware Development of Ethernet Gateway Based on ISO26262

文章结合以太网网关的硬件设计,阐述在得到相应安全目标后,如何基于ISO26262进行安全等级的分解、器件的选型、硬件的设计及硬件功能安全相关参数的计算。通过文章所提出的硬件设计注意事项,设计了一款满足功能安全要求的以太网网关。

Combined with the hardware design of Ethernet gateway,this paper expounds how to decompose the security grade,select the components,design the hardware and calculate the safety parameters of the hardware design based on ISO26262 after getting the corresponding security goal.Through the hardware design considerations presented in this paper,an Ethernet gateway is designed to meet the functional security requirements.
