Embodiments of techniques and systems for protected access to virtual memory are described. In embodiments, a protected memory management architecture ('PMMA') may be configured to control accesses to protected physical memory. The PMMA may provide a protected virtual memory window for dynamic allocation of protected memory regions. During forward translation of virtual memory addresses, the PMMA may check a region ID of a process before allowing access. During reverse translation of a physical memory address, the PMMA may prevent accesses to protected physical memory addresses. The PMMA may also dynamically allocate physical memory to protected memory regions in virtual memory and may authenticate the physical memory as available before allocation. Other embodiments may be described and claimed.
