“…Addition, subtraction, and multiplication, are arithmetic operations that can be performed independently and parallel in various residue channels more effectively than in the conventional binary systems. The adoption of RNS has offered notably effective improvements for distinct types of DSP applications [10].…”

Security is a very vital concern in information system in this modern day. The protection of confidential files and integrity of information kept in the database are also of great important, the security model play an important role in protecting the privacy and integrity of messages in the database from unlawful users is a formal method to verify and describe intricate information system. An access Control mechanism is a main strategy for prevention and protection of the classified files in a database; this is carried out by restricting rights of access for different approved users of these files. This paper proposes a novel access control mechanism based on Chinese remainder theorem II which implements a single-key-lock system to encrypt one key called a secret key which is used for both encryption and decryption in the electronic information system for accessing the database. The key to be used in the decryption process must be exchanged between the entities in communication using symmetric encryption for the users to have access to the database. This method represents flocks and keys which is highly efficient and proficient. Also, this implementation can be achieved using the Chinese remainder theorem which executes faster operations and enables simpler construction of keys and locks to be provide for user to have access to control.
