Abstract:
The emergence of quantum computers presents a serious challenge to the widely used public-key cryptographic algorithms, including RSA and Elliptic Curve Cryptography (ECC), that are currently central to the digital security landscape. Meanwhile, new technologies such as Sixth Generation(6G) communication networks, the Internet of Things (IoT), blockchain platforms, and cloud computing infrastructures must also be equipped with strong and scalable security measures to safeguard sensitive information and communications. Post-Quantum Cryptography (PQC) has been one of the solutions that has been suggested as a strong potential solution that offers cryptographic algorithms that are secure against quantum attacks as well as classical attacks and is compatible with current digital systems. This review paper provides a detailed survey of recent advances in PQC that include the most important cryptographic families including lattice-based, code-based, and hash-based cryptography. The National Institute of Standards and Technology (NIST) standardization efforts are discussed in detail, such as ML-KEM (Kyber), ML-DSA (Dilithium), Falcon, and SPHINCS+. Over two dozen recent research papers are evaluated to test the security, performance, implementation and practicality of PQC algorithms in limited resource settings.
