Computer configuration for interfacing to a secure data carrier

摘要

A computer configuration interfaces to a secured data body with data storage, for therewith exchanging confidential information along a logical link that maps transiently on a physical link. In particular, a bidirectional interruption facility is present on the physical link that is bridged by a controller. The interruption is made operational through recognizing an appropriate control signal on the physical link that signals a forthcoming exchange. This makes data transfer mandatory through the controller.
