A New Access Control Method Using Prime Factorisation
Jing‐Jang Hwang, Binhong Shao, P. C. Wang · The Computer Journal · 1992
Based on prime factorisation in number theory, a new but simple and efficient protection method for access control is proposed. This method has several advantages on performance over previous methods in the literature. Especially, a file/user can be added to or removed from the system without much effort. Excellence of this method is more pronounced for those systems where files are accessible to only a few users.
