Zusammenfassung: | A processor receives, from a requestor, a first request containing a virtual address. Based on the first request, the processor determines a real address corresponding to the virtual address, encrypts at least a portion of the real address to obtain a cryptographic secure real address, and returns the cryptographic secure real address to the requestor. Based on receiving a second request specifying a request address, the processor decrypts the request address to validate the request address as the cryptographic secure real address. Based on validating the request address as the cryptographic secure real address, the processor allows access to a resource of the data processing system identified by the real address. |
