It looks to me that having a standalone chip is not great in general due to hardware attacks: you can easily MITM the system bus for example. Whereas a number of attacks become much harder once you use an integrated secure element. The form factor of the iPhone of course almost makes the T2 secure enclave an integrated secure module. I also don’t think hardware attacks are really considered anyway (and as we see most researchers focus on software attacks) |
