Distributed and independent access to quantum encrypted cloud database

The cloud database as a service helps in several internet based applications, but it faces several confidentiality problems. Hence to improve data confidentiality in terms of scalability and availability, a new model namely Security as a Service (SECaaS) model is being introduced that uses quantum encryption scheme. Quantum cryptography is rapidly developing these days due to its high secrecy power in terms of key generation and key distribution. Hence this quantum encryption scheme is used in layered concept that helps to improve data confidentiality and secrecy.
