That Bluefin was my daily ever since it’s relaunch in 2024. ...

A tutorial I authored is finally available in the official AWS documentation!! https://docs.aws.amazon.com/greengrass/v2/developerguide/gg-with-tpm-tutorial.html What is it about?

Why would one do this? Let’s take this scenario, your business operates a fleet of Cloud native Endpoints (basically computer/devices that talk to the cloud). This could be devices like point of sale systems, embedded devices, industrial PCs, any computer you probably see out in the wild that isn’t a personal computer. ...

The Trusted Platform Module, or TPM, is similar to a smart card device in that it is a small footprint low cost security module typically implemented as a tamper resistant integrated circuit (IC). The TPM however, has been specifically designed to be a building block for trusted computing ...
