Cryptography is used to ensure the security of two-party communications. Transmission of secret messages is the most prevalent cryptographic concern. The protocol for maintaining confidentiality is cryptographic. Security in quantum cryptography is based less on mathematical problem-solving and more on scientific foundations, such as quantum physics and statistics. One popular usage of quantum cryptography is in the creation of cryptographic keys for use in communication, known as quantum key distribution (QKD). Security is ensured and eavesdropping is prevented since it is based on the Heisenberg uncertainty principle. The topics of weak laser-based quantum cyphers, polarisation coding, phase coding, and frequency coding have all received a significant amount of attention.

11.1 Introduction

In recent years, Information Technology and Communication have witnessed remarkable growth. Cryptography is the method that is used to safeguard communication between parties from adversaries. The main goals of cryptography are authentication (the message is received from an authorised source), secrecy (no one ...
