摘要

近年来，软件的规模越来越大，软件安全事件也越来越多。《民用机载系统和设备安全评估过程指南和方法》(ARP4761)是SAE国际发布的航空航天推荐实践，它提供了系统的安全评估过程，以解决系统的安全问题。在ARP4761中，过程FHA和FTA根据软件开发标准(如DO-178C)确定软件开发级别，安全审核员认为只要软件开发过程以软件开发标准为指导，软件就是安全的。然而，航空软件规模的不断扩大导致了越来越多的软件安全问题，软件的开发标准并不能保证软件不存在安全问题。分析软件的安全性显得尤为重要。提出了FMEA在ARP4761软件安全分析中的应用方法，并对ARP4761软件安全评价进行了改进。

An Airborne Software FMEA Application Method Based on ARP4761

In recent years, software has grown in size and software safety incidents have also increased. Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment (ARP4761) is an aerospace recommended practice from SAE International, it provides a safety assessment process of the system to solve the safety problem of the system. In ARP4761, the process FHA and FTA determine the software development level based on the software development standard (such as DO-178C) and safety reviewer thought that the software is safe as long as it's development processes are guided by software development standards. However, increasing airborne software scale is causing more and more software safety problems and the development standard of software can't guarantee that there is no safety problem in software. It is especially important to analyze the safety of the software. This paper presents the application method of FMEA in software safety analysis based on ARP4761 and improves the software safety evaluation of ARP4761.
