Amazon EC2 支援 NitroTPM 與 UEFI Secure Boot

也是在清 RSS reader 的時候翻到的公告,在兩個禮拜前 AWS 宣佈 Amazon EC2 支援 NitroTPMUEFI Secure Boot:「Amazon EC2 Now Supports NitroTPM and UEFI Secure Boot」。

NitroTPM 相容於 TPM 2.0 的界面,所以有支援 TPM 2.0 的軟體都可以利用 (像是 Windows 11):

Nitro Trusted Platform Module (NitroTPM) is a virtual device that is provided by the AWS Nitro System and conforms to the TPM 2.0 specification.

之前在研究 LUKS 的時候也有看到 TPM 相關的資料:

Linux Unified Key Setup (LUKS) or dm-verity on Linux are examples of OS-level applications that can leverage NitroTPM too.

然後支援的平台有些限制,只有 IntelAMD 的平台有支援,而且還要扣掉 Xen、Mac 以及 bare metal 的機種:

At the moment, we support all Intel and AMD instance types that supports UEFI boot mode. Graviton1, Graviton2, Xen-based, Mac, and bare-metal instances are not supported.

ARM 那邊有自己的一套,不太玩 TPM 大概可以理解,Xen 大概是不想支援 (停止開發新功能之類的原因),Mac 可能是 Apple 的硬體限制,最後的 bare metal 是因為沒辦法虛擬化?

然後這個功能不另外收費,看起來幾乎是全球性一次更新:

There is no additional cost for using NitroTPM. It is available today in all AWS Regions, including the AWS GovCloud (US) Regions, except in China.
