Demystifying the Secure Enclave Processor

Explore the inner workings of Apple's Secure Enclave Processor (SEP) in this 48-minute Black Hat conference talk. Delve into the hardware design, boot process, and architecture of SEPOS, the operating system running on the SEP. Learn about the mailbox mechanism facilitating data exchange between iOS kernel and SEP, and how SEPOS handles and relays this information to its services and applications. Evaluate the SEP's attack surface and discover potential vulnerabilities uncovered by the presenters' research. Gain insights into this crucial security component, introduced with the iPhone 5S, designed to protect sensitive data like fingerprint information and cryptographic keys from potential attackers.
