TPM chip on iPhone

Question

Do Apple devices ship with a TPM chip? My Mac doesn't have a TPM chip, but does an iPhone have of a TPM chip or how do I determine if the iPhone has a TPM chip or not? On my Mac, I use this command to check if TPM chip is there or not: ioreg -x | grep TPM.

Answer 1

I'm assuming that your TPM reference stands for "Trusted Platform Module."

According to Wikipedia:

Due to legal restrictions TPMs may not be deployed in a number of countries. Possible reasons for these legal restrictions include the fact that state security services may not be able to access data or keys secured with a TPM.

• China
• Russia
• Belarus
• Kazakhstan

Since Apple sells iPhones in China (see this NY Times article), we can infer that the iPhone doesn't ship with TPM chips.
