Abstract
A computing system, comprising includes a first central processing unit (CPU) and a second CPU coupled with the first CPU and with a host processor. The second CPU and the host processor may both request the first CPU to generate keys that have access rights to regions of memory to access specific data. The first CPU may be configured to, in response to a request from the second CPU, generate a unique key with a unique access right to a region of memory, the unique key usable only by the second CPU, not the host processor.
