Abstract:

The report is a feasibility study of a technique using a one-time password on a magnetic card as a means of user identification for computer terminal access. A magnetic card readerrecorder was interfaced with a PDP-1120 computer to provide a demonstration model. Interface logic diagrams and detailed description of the software used in the demonstration model are included. A method is shown for calculating the size of the major elements of the software required for implementation in any computer system. The report outlines some requirements of computer operation system in which identification feature is eventually used. Author
