Summary:Encrypted memory access using page table attributes is disclosed. One example is a memory system including a memory controller at a memory interface. The memory controller includes an encryptor to control a plurality of memory access keys respectively associated with memory regions, where each memory region is allocated to a respective client, and an access manager to receive an access request from a client, the access request including a client access key to access a memory element. The access manager looks up a memory access key from a page table attribute associated with a physical address of the memory element, and determines if the access request is valid by comparing the client access key with the memory access key associated with the memory region that includes the memory element. Based on the determination and a mode of operation, the access manager provides a response to the access request.
