Ask HN: Does the iPhone have a TPM (Trusted Platform Module)?

I was reading a paper on the disadvantages of the DP-3T contact tracing protocol: https://eprint.iacr.org/eprint-bin/getfile.pl?entry=2020/399&version=20200409:125022&file=399.pdf

It concludes that its biggest pitfall can be fixed by relying on a TPM.

Does the iPhone have such module? In what form?

The closest I got to an actual answer is: https://apple.stackexchange.com/questions/53676/tpm-chip-on-iphone
