A Survey on Classical and Quantum Cryptography

Conventionally, every individual’s personal data is been digitalized but as the digital theft could arise from hackers residing anywhere in the world, there is a need of huge improvement towards the security of an electronic data. Nowadays, in order to make the existing security system more robust and secure the research work is abundantly increasing day by day. The extra data/information we share which is confidential, greater is the risk of us falling to a data/information breach that is intentionally or unintentionally sharing of personal details to the unauthorized third parties. Now the hackers being intelligent and able to crack the currently available encryption methods, hence the scope for building uncrackable codes is more. This paper tries to summarize the view of top cybercrimes and different assets of Classical, Quantum and Post quantum cryptography to magnify the security of existing system.
