Experimental Perspectives of Post and Pre Quantum Cryptographic Algorithm for Cyber Physical Systems in IoT

In the realm of data indemnity and cryptography, the evolution of cryptographic algorithms has been profound, reflecting the eternal battle between encryption techniques and decryption capabilities. This paper delves into the dichotomy of primitive cryptography and post-quantum cryptography, specifically exploring their implementation and performance on M4 Cortex embedded systems. By studying their characteristics, strengths, and weaknesses, we aim to shed light on the implications and considerations for secure communication in the face of advancing computational capabilities and emerging threats.
