[1] [2] SGX is designed to be useful for implementing secure remote computation, secure web browsing, and digital rights management (DRM). [3] Other applications include concealment of proprietary algorithms and of encryption keys. [4] SGX involves encryption by the CPU of a portion of memory (the enclave).
The secure enclave itself is a flashable 4 MB AKF processor core called the secure enclave processor (SEP) as documented in Apple Patent Application 20130308838. The technology used is similar to ARM's TrustZone/SecurCore but contains proprietary code for Apple KF cores in general and SEP specifically.
The secondary processor in T2 is an 32-bit ARMv7-A based CPU called Secure Enclave Processor (SEP) which has the task of generating and storing encryption keys. It is running an operating system called "sepOS" based on the L4 microkernel .
The first security level, Profile 1, was targeted against only software attacks, while Profile 2, was targeted against both software and hardware attacks. [ 4 ] Commercial TEE solutions based on ARM TrustZone technology, conforming to the TR1 standard, were later launched, such as Trusted Foundations developed by Trusted Logic.
Apple A series processors beginning with the A7 contain a Secure Enclave coprocessor running an L4 operating system [14] called sepOS (Secure Enclave Processor OS) based on the L4-embedded kernel developed at NICTA in 2006. [15] As a result, L4 ships on all modern Apple devices including Macs with Apple silicon. In 2015 alone, total shipments ...

The file also holds the kernel caches, and a "Firmware" folder which contains iBoot, LLB (Low-Level Bootloader), iBSS (iBoot Single Stage), iBEC (iBoot Epoch Change), the Secure Enclave Processor firmware, the Device Tree, Firmware Images (Apple logo, battery images, Recovery mode screen and more), baseband firmware files in .bbfw format ...
Shares of Intel were up 5.7% after the announcement. The administration's focus on the Secure Enclave reflects a broader strategy to enhance national security through targeted investments in ...
