Demystifying the Secure Enclave Processor

Conclusion (Continued)
• Overall hardware design is light years ahead of
competitors
▫ Hardware Filter
▫ Inline Encrypted RAM
▫ Generally small attack surface
• But it does have its weaknesses
▫ Shared PMGR and PLL are open attack to attacks
▫ Inclusion of the fuse source pin should be re-evaluated
▫ The demotion functionality appears rather dangerous
Why does JTAG over lightning even exist?
