TL;DR: In this paper, an electronic funds transfer system (EFT) is described in which retail terminals located in stores are connected through a public switched telecommunication system to card issuing agencies data processing centers.
Patent
Controlling the use of cryptographic keys via generating station established control values
TL;DR: In this paper, a method for controlling the use of a cryptographic key at a using station by a generating station in a network of generating and using stations is disclosed, where the key and control value are authenticated via a special authentication code before use by the using station and coupled during key generation such that the key is recovered only if a correct control value is specified.
