E91 QKD protocol for authentication in online banking systems

Online banking is a new industry which allows people to interact with their banking accounts via the internet from virtually anywhere in the world. In this system, a strong security system is used but sometimes it is not so much effective. Security of the overall online banking system is reduced to that of the classical approach used for authentication, which could be merely computationally secure rather than unconditionally secure. Thus, for the authentication purpose the concept of quantum cryptography comes into the picture. When quantum cryptography enters widespread public use it will only protect data in transit across public networks. But we are using this quantum cryptography for enhancing the authentication process for user authentication in online banking system. The use of E91 protocol in the authentication does give unconditional security that is what we are going to discuss in this paper. The ultimate goal is to make online banking systems more reliable, integrate it with E91 protocol for the user authentication.
