Abstract
According to one or more embodiments of the present invention, a computer implemented method includes receiving, at a secure interface control of a computer system, an access request for a data structure related to a secure entity in a secure domain of the computer system. The secure interface control can check for a virtual storage address associated with a location of the data structure. The secure interface control can request an address translation using a virtual address space of a non-secure entity of the computer system based on determining that the location of the data structure is associated with the virtual storage address. The secure interface control can access the data structure based on a result of the address translation.
