了解遥遥领先的Renesas晶振的RX安全解决方案

来源：http://yijindz.com 作者：yijin 2023年09月23

为了应对物联网设备日益增长的威胁，RX 提供了整个物联网设备生命周期内的安全解决方案，用于自主安全防护，以及从设计阶段到生命周期结束的安全防护。物联网端点设备自主安全防护由瑞萨电子的专用硬件安全 IP (Trusted Secure IP) 提供。

网络环境下的物联网设备经常暴露在各种威胁之中。然而，如果物联网端点设备本身是安全的，它便可保护自己，抵御威胁，并阻止恶意和未经授权的行为，即使在不安全的网络环境也是如此。RX 具有使用Renesas瑞萨晶振专用硬件安全 IP (Trusted Secure IP) 的强大安全技术，为物联网端点设备提供自主的安全防护。

RX 安全解决方案

RX Security Solutions

硬件：RX 微控制器采用安全硬件 IP，可抵御威胁

RX 配备“Trusted Secure IP”，无法从外部访问。Trusted Secure IP 中的关键数据和加密引擎受到严格保护。它还结合区域保护功能和 RX 特定的功能，保护认证程序免受篡改威胁。有了该产品，您可以构建具有信任根的系统，以提供自我维持的安全防护，并轻松提供强大的保护，以抵御各种威胁。

使用 RX 安全解决方案实现 DLM

在用户产品的生命周期中，存在着各种威胁。您不仅需要设备的安全特性，还需要在整个生命周期中进行安全操作来应对这些威胁。这种思维方式被称为“设备生命周期管理 (DLM)”。RX 安全解决方案支持 DLM，同时让产品生命周期操作方面的稳健和高级安全管理成为可能。

认证

符合国际安全标准的通用 MCU

搭载Trusted Secure IP的RX微控制器已经通过适用于HSM*1与IC卡的NIST*2的 FIPS*3140-2 三级CMVP认证，是一种坚固且可靠性高的通用微控制器。另外，Trusted Secure IP中的各种加密算法也都已经通过CAVP认证，因此用户可以放心使用。
