Generation of cyptographic signatures for data access
摘要
The transmission of security data is made with the inclusion of an electronic signature that has to be present before the data can be read. As protection against the manipulation of the signature data the information is generated by an external unit coupled by an interface rather than the system computer. Data is transmitted to a printer or some form of display.
