A Comparative Performance Evaluation of Kyber, sntrup761, and FrodoKEM for Post-Quantum Cryptography

Abstract: Post-quantum cryptography (PQC) aims to develop cryptographic algorithms that are secure against attacks from quantum computers. This paper compares the leading postquantum cryptographic algorithms, such as Kyber, sntrup761, and FrodoKEM, in terms of their security, performance, and real-world applicability. The review highlights the strengths and weaknesses of each algorithm and provides insights into future research directions. We also discuss the challenges of transitioning from classical to post-quantum systems and the potential impacts on various industries. This paper serves as a foundation for understanding the current state of post-quantum cryptography and its future prospects in the quantum computing era.
