Abstract

This chapter discusses the significance of quantum cryptography in securing communication channels for the future. It highlights the challenges posed by quantum computing to traditional cryptographic systems and the potential solutions offered by quantum-resistant protocols. The chapter emphasizes the transition from classical to quantum-resistant cryptography, highlighting hybrid cryptosystems, algorithm agility, and standards development. It discusses the vulnerability of classical cryptographic systems to quantum algorithms, such as Shor's and Grover's algorithms. It also explains the concept of hybrid cryptosystems, which combine classical algorithms with post-quantum key exchange protocols.
