Abstract
Inception of “quantum supremacy” officially announced by Google has given rise to future threats to data security and privacy. One of the areas that we must focus on is the future threats to all applications dependent on IT, not just restricted to military applications, power distribution, smart cities but all automated infrastructures (especially critical infrastructure). The objective of the study is to make the community aware of the current and future threats to data security and privacy using future quantum applications. The paper mainly demonstrates how PKI and its key exchange method can be compromised easily with the help of quantum computers and also proposes a solution to make our key exchange protocol secured, using QKD which ensures a hackproof exchange of keys between the sender and intended receiver. The paper also explores the research observation areas that can be focused on, for protecting against future threats emerging due to quantum evolution.
