A Binary Single-Key-Lock System for Access Control
October 1989 (vol. 38 no. 10)
pp. 1462-1466
A binary coding method was invented and has been applied to the single-key-lock (SKL) system which achieves access control by associating with each accesser only one key and with each resource only one lock. The new system is called the binary single-key-lock (BSKL) system. In both the SKL and BSKL systems, through operations on the single-key-lock pair, the control information can be revealed.
