随着汽车联网程度的提高,其结构也变得越来越复杂,越发依赖高度集成的电子元件。向高速车内网络高速车-云连接发展的趋势提高了市场对作为车内和外部通信中心枢纽的高性能智能网关的需求。智能网关的设计必须确保高水平的数据交换处理能力,建立高水平安全防护,保护驾驶人员免受潜在的网络攻击,这些攻击可能会将恶意数据注入汽车系统,从而可能危及驾驶人员安全或侵犯数据隐私。安全网关作为坚固耐用、性能可靠的节点用于从云端进行无线软件更新、预测性维护分析(以避免系统故障)、车载诊断,以及车内安全通信。   阅读更多

ST’s turnkey solution for flawless security in smart automotive gateways

At the heart of every smart gateway is an automotive-grade microcontroller, specifically designed to enable security functions. The architecture of ST’s automotive MCUs offers performance and high throughput, which are essential to enable the real-time execution of various in-vehicle applications and the support of evolving communication protocols, while ensuring high security standards.

Based on a robust design embedding a reliable, isolated Hardware Security Module (HSM), SPC58 Chorus MCUs provide efficient, state-of-the-art data encryption and can execute authentication flows and message integrity checks, while running secure protocols. Their embedded HSM relies on its own independent CPU, internal RAM, and NVM, which are separated from the main CPU and application software, thus isolating the security subsystem and preventing potential cyber-attacks.

In addition, for further protection, the ST33G1M2A secure element can be used in conjunction with ST’s HSM-based automotive MCUs to reach EAL5+ Common Criteria certification. The ST33G1M2A delivers a tamper-proof solution to secure the storage of secret keys and data. Cryptographic services for secure boot, authentication, encryption, signature generation and verification, as well as local and remote attestation services can also be safely partitioned and run on this device.
