Abstract: A method is provided. A secure interface control in communication with an untrusted entity perform the method. In this regard, the secure interface control implements an initialization instruction to set donated storage as secure. The implementing of the initialization instruction is responsive to an instruction call issued from the untrusted entity.

Abstract: According to one or more embodiments of the present invention, a computer implemented method includes initiating, by a non-secure entity that is executing on a host server, a secure entity, the non-secure entity prohibited from directly accessing any data of the secure entity. The method further includes injecting, into the secure entity, an interrupt that is generated by the host server. The injecting includes adding, by the non-secure entity, information about the interrupt into a portion of non-secure storage, which is then associated with the secure entity. The injecting further includes injecting, by a secure interface control of the host server, the interrupt into the secure entity.

Abstract: A method is provided by a secure interface control of a computer that provides a partial instruction interpretation for an instruction which enables an interruption. The secure interface control fetches a program status word or a control register value from a secure guest storage. The secure interface control notifies an untrusted entity of guest interruption mask updates. The untrusted entity is executed on and in communication with hardware of the computer through the secure interface control to support operations of a secure entity executing on the untrusted entity. The secure interface control receives, from the untrusted entity, a request to present a highest priority, enabled guest interruption in response to the notifying of the guest interruption mask updates. The secure interface control moves interruption information into a guest prefix page and injecting the interruption in the secure entity when an injection of the interruption is determined to be valid.

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.

Abstract: A method is provided. The method is implemented by a communication interface of a secure interface control executing between the secure interface control of a computer and hardware of the computer/ In this regard, the communication interface receives an instruction and determines whether the instruction is a millicoded instruction. Further, the communication interface enters a millimode comprising enabling the secure interface control to engage millicode of the hardware through the communication interface based on the instruction being the millicoded instruction. The millicode, then, executes the instruction

Abstract: De acuerdo con una o más modalidades de la presente invención, un método implementado por computadora incluye recibir, en un control de interfaz segura de un sistema de computadora, una solicitud de acceso para una estructura de datos relacionada con una entidad segura en un dominio seguro del sistema de computadora. El control de interfaz segura puede verificar una dirección de almacenamiento virtual asociada con una ubicación de la estructura de datos. El control de interfaz segura puede solicitar una traducción de direcciones usando un espacio de dirección virtual de una entidad no segura del sistema de computadora con base en la determinación de que la ubicación de la estructura de datos se asocia con la dirección de almacenamiento virtual. El control de interfaz segura puede acceder a la estructura de datos con base en un resultado de la traducción de direcciones.
