Public key digital contents confidentiality scheme based on quantum spin and finite state automation

Numerous encryption plans are legitimately founded on the transformation of frameworks or by characterizing the strict guidelines. Most of the security systems are based on mathematical structures and their applications in diverse applied sciences. We propose here an advanced digital contents confidentiality scheme to simulate the phenomenon rather than creating rigid rules. We operate digital data trailed by quantum spin states for specific phase and finite state machine for limited number of rounds. The extent of the presented article revolves around the development and deployment of public key cryptosystem basis on the concepts of quantum spin states and finite state machine effectively. Both states (spin and finite state machine) provide the high degree of naturalness contrasted with ordinary cryptosystem. (C) 2019 Published by Elsevier B.V.
