An Access Control Mechanism Based on the Generalized Aryabhata Remainder Theorem
並列摘要
An access control mechanism is a technology to protect the confidential files stored in a database by restricting the access rights of different approved users of these files. In this paper, we propose a novel access control mechanism using the single-key-lock system and the generalized Aryabhata remainder theorem (GART), in which each user is associated with a key and each digital file with a lock. Our mechanism possesses three unique features, 1) a high efficiency of constructing the keys for the users and the locks for the files; 2) a simple operation on the user's key and on the file's lock allows the user access to the file; and 3) the keys for adding or deleting a user can be updated easily without affecting the existing keys for other users.
