TPM(Trusted Platform Modeule),是一种基于内嵌了加密功能的安全控制器的硬件设备。它协同它支持的软件和固件一起工作，并能够阻止对笔记本电脑的非授权访问。TPM包含一个硬件引擎，可以对数据进行2048位的RSA加密。TPM使用内建的RSA加密引擎对数字签名和按键映射进行加密。

Trusted Platform Module (TPM) is a hardware device that is basically a secure micro-controller with added cryptographic functionalities. It works with supporting software and firmware to prevent unauthorized access to a notebook computer. The TPM contains a hardware engine to perform up to 2048-bit RSA encryption/decrypti on. The TPM uses its built-in RSA engine during digital signing and key wrapping operations.
