设计保障级别 Design Assurance Levels(DALs) DO-178B引入了(并且DO-178C继续使用)设计保证级别(DAL)的基本概念,该概念根据对飞机安全的贡献程度定义了应由设计保证流程应用的严谨程度。DAL越高,作为设计保证流程一部分必须执行和完成的活动和目标就越多,因为软件发生故障或失效可能对飞机造成的后果更为严重。设计保证...
DO-178B引入(并DO-178C继续使用)了设计保证级别(DAL)的基本概念,该概念根据对飞机安全的贡献来定义设计保证过程应该应用的严格程度。DAL越高,由于软件失败或故障对飞机造成的后果更为严重,设计保证过程就必须执行和达到更多的活动和目标。 设计保证过程的基本结构包括三个组成部分: 计划 开发 积极过程(验证、配置管理...
Table 1: DO-178C Design Assurance Levels (DAL) The “Objectives” column of Table 1 lists the number of DO-178C objectives that must be met by the software in the overall DO-178C process. Some of these objectives are fulfilled in each of the six key areas, with verification fulfilling...
为了帮助航空工程师保护他们的航空电子软件和系统,wolfSSL在其商业现成的 wolfCrypt 引擎中添加了对 RTCA DO-178C 设计保证级别 (DAL) A 的完全支持,这是一个轻量级、基于 ANSI C 的加密库,符合 FIPS 140-2 证书 2425 和 3389。 DO-178C 是航空当局用来批准在航空航天环境中使用商用现货 (COTS) 软件的认证文...
Design Assurance Levels (DALs) DO-178B introduced (and DO-178C continued to use) the fundamental concept of the Design Assurance Level (DAL), which defines the amount of rigor that should be applied by the design assurance process based on the contribution to Aircraft Safety. The higher the...
The DO-178 standards require that all airborne software be assigned a Design Assurance Level (DAL) based on the potential effects of a failure in the system, ranging from the lowest level E (“No Effect”) to the highest level A (“Catastrophic”). The standards also outline various process...
DAL C – Major – 62 Objectives need to be satisfied. DAL D – Minor – 26 Objectives need to be satisfied. DAL E – No Effect – No Safety Effect The following tables provide an overview of the mandatory software lifecycle data for all DAL levels, including DAL E. A...
DAL A DO-178C Certification Standard DO-178C is a certification standard for software used in airborne systems. It concentrates on objectives for software life-cycle processes to assure the development of safe and reliable software for airborne environments. DO-178C determines five Safety levels by...
Phoenix, AZ – September 19, 2023 – DDC-I, a leading supplier of software and professional services for mission- and safety-critical applications, today announced that it has completed multicore DO-178C verification to Design Assurance Level A (DAL A) f
178. In addition, any of the FIPS 140-3 validated crypto algorithms can be used in DO-178 mode for combined FIPS 140-3/DO-178 consumption. The wolfCrypt cryptography library has been FIPS 140-3 validated (Certificate #4718). For additional information contactfips@wolfssl.comordo178@wolfssl....
