    This paper examines guarded pointers, a hardware technique which uses tagged 64-bit pointer objects to implement capability-based addressing. Guarded pointers encode a segment descriptor into the upper bits of every pointer, eliminating the indirection and related performance penalties associated with traditional implementations of capabilities.Cited by: 123

Capability-based addressing - Wikipedia

    https://en.wikipedia.org/wiki/Capability-based_addressing
    In computer science, capability-based addressing is a scheme used by some computers to control access to memory. Under a capability-based addressing scheme, pointers are replaced by protected objects (called capabilities) that can be created only through the use of privileged instructions which may be executed only by either the kernel or some other privileged process authorised to do so.
