摘要： Methods and apparatus relating to lightweight trusted tasks are disclosed. In one embodiment, a processor includes a memory interface to a memory to store code, data, and stack segments for a lightweight-trusted task (LTT) mode task and for another task, a LTT control and status register including a lock bit, a processor core to enable LTT-mode, configure the LTT-mode task, and lock down the configuration by writing the lock bit, and a memory protection circuit to: receive a memory access request from the memory interface, the memory access request being associated with the other task, determine whether the memory access request is attempting to access a protected memory region of the LTT-mode task, and protect against the memory access request accessing the protected memory region of the LTT-mode task, regardless of a privilege level of the other task, and regardless of whether the other task is also a LTT-mode task.

摘要： Execution-Aware Memory protection technologies are described. A processor includes an instruction fetch unit to fetch instructions of applications executing in a multitasking environment and an execution unit to execute the instructions. A memory protection unit (MPU) enforces memory access control of the applications by defining an instruction region (I-space) and a data region (D-space and linking the I-space to the D-space. When the MPU determining whether an instruction address is within the I-space and whether a data address of a data access operation is within the D-space. The MPU issues a memory protection fault for the data access operation when either the instruction address is not within the I-space or the data address is not within the D-space.

摘要： Methods, apparatus, and system to create interrupts which are resolved at runtime relative to an active compartment. Active compartments may be, for example, a compartment of an operating system (“OS”) or a trusted execution environment (“TEE”). The context-specific interrupts comprise an interrupt dispatch table (“IDT”) for each compartment.

摘要： Systems, apparatuses and methods may provide for changing the execution mode of a device based on policy enforcement request that is received when the device is located proximately to a specific area. The policy enforcement request is verified with respect to a System on Chip (SoC) platform. An enforcement manager of the SoC platform may enforce the received policy enforcement request if verification is successful, and an attestation controller may report the enforced policy request and a status of the platform to an external device from which the policy request originates.
