摘要：Distributed database plays an important role in business environment. The major problem that we face in normal database is that failure at one point means overall failure, but in distributed database single point of failure problem is removed as database is distributable to many locations if there is failure at one point we can access data from the other location. An important area of research in this field provide security to database system. In this work of research, the 4 layered architecture is been developed with introduction of a strong encryption algorithm called NTRU. The four layered architecture is been developed for the purpose of high security which is needed to secure the highly confidential database systems. Each level have its own significance. All the parameters of security is fulfilled by the approach on four levels. No malicious users can interfere with the system, attacks such as brute force are successfully overcomes. The NTRU will save all the data in form of private and public key along the network saving the data from man in middle attacks.
