Abstract

Quantum computing brings about a new problem to traditional cryptographic algorithms; it violates the security of current encryption methods. This chapter is concerned with investigating two areas, quantum cryptography and post-quantum security measures, detailing their concepts, developments, and consequences. Quantum cryptography utilizes the principles of quantum mechanics and particularly makes use of superposition and entanglement. Post-quantum cryptography (PQC), on the other hand, is an approach to constructing cryptographic algorithms that will be immune to quantum attacks while at the same time keeping compatibility with classical methods. The chapter focuses on the aspects of integration between quantum cryptographical advancements and post-quantum algorithmic progressions and mutual distinctions have been explained. Possible shortcomings to scalability, implementation, and standardization issues of both approaches are discussed, as well as an examination of combined QKD and post-quantum algorithms architectures.
