Security identification of printed circuit board

The invention relates to a security identification for a printed circuit board. Examples described herein relate to a printed circuit assembly (PCA). The PCA includes a printed circuit board (PCB). The PCA further includes an identification device embedded in the PCB. The identification device stores identity information that uniquely identifies the identification device and the PCB. Furthermore, a PCB identifier defined using the identity information is also stored in a platform attestation file hosted at the PCA local, a remote server, or both the PCA local and the remote server. In addition, the PCA comprises an authentication device arranged on the PCB, and the platform attestation file is bound to the authentication device in a password mode. 本公开涉及印刷电路板的安全标识。本文中描述的示例涉及一种印刷电路组件(PCA)。所述PCA包括印刷电路板(PCB)。所述PCA进一步包括嵌入PCB中的标识设备。所述标识设备存储对标识设备和PCB进行唯一地标识的身份信息。此外，使用所述身份信息定义的PCB标识符还存储在平台证明文件中，所述平台证明文件托管在所述PCA本地、远程服务器、或者所述PCA本地和所述远程服务器两者上。另外，所述PCA包括设置在所述PCB上的认证设备，其中，所述平台证明文件以密码方式绑定到所述认证设备。
