关于客户
Savari 为汽车制造商、汽车售后市场和智慧城市构建软件和硬件传感器解决方案。
挑战
V2X 系统使用复杂的基于公钥基础设施 (PKI) 的方法来促进可信通信:
- V2X 系统使用椭圆曲线密码术 (ECC)。设备必须能够安全有效地生成 ECC 密钥
- 随机数生成器必须具有高熵
- 必须通过使用安全存储来保护根证书
- 设备必须具有防篡改功能,包括物理攻击
- 私钥必须具有防止侧信道攻击的保护
- 必须保护和安全使用私钥 › V2X 设备需要每秒生成多达 40 条消息。签名延迟必须低才能支持此频率
解决方案
Savari 已将英飞凌的 eSE 集成到其售后市场车载设备 (OBE) 和路边设备 (RSE) 设备中。
Savari 堆栈使用第三方安全模块,根据标准(例如 IEEE 1609.2)实现相关的 V2X 安全协议。 Savari 和英飞凌合作为 Savari 堆栈中的安全模块和其他组件创建了一个应用程序编程接口 (API)。使用此 API,V2X 堆栈可以安全地与 HSM 通信并使用其服务执行必要的操作
Savari 还开发了工具和实践,以将 eSE/HSM 完全集成到设备引导和安全凭证配置工作流中,以实现端到端符合 US-DOT/SCMS/CAMP(Crash Avoidance Metrics Partners)标准。图 4.0 显示了工作流程。

Case Study
Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).
Case Study
Monitoring of Pressure Pumps in Automotive Industry
A large German/American producer of auto parts uses high-pressure pumps to deburr machined parts as a part of its production and quality check process. They decided to monitor these pumps to make sure they work properly and that they can see any indications leading to a potential failure before it affects their process.
