This hack shouldn't work against iPhones, right? Even with full physical access to the phone, power analysis with physical tools was unable to extract keys from the secure enclave. Moreover, since the key is physically burnt into the silicon, shouldn't that mean it shouldn't be extractable via power analysis anyway?
- jnwatson 9y agoThis isn't a power analysis attack. This is a fault injection attack. If cryptography is being done in software and the trusted core voltage and/or frequency is controllable by the attacker, the iPhone could be vulnerable.
