Abstract

A processor cache is logically partitioned into a main partition, located in the cache itself, and an enclave partition, located within an enclave, that is, a hardware-enforced protected region of an address space of a memory. This extends the secure address space usable by and for an application such as a software cryptoprocessor that is to execute only in secure regions of cache or memory.
