Post-Quantum Security: Opportunities and Challenges

Abstract

Cryptography is very essential in our daily life, not only for confidentiality of information, but also for information integrity verification, non-repudiation, authentication, and other aspects. In modern society, cryptography is widely used; everything from personal life to national security is inseparable from it. With the emergence of quantum computing, traditional encryption methods are at risk of being cracked. People are beginning to explore methods for defending against quantum computer attacks. Among the methods currently developed, quantum key distribution is a technology that uses the principles of quantum mechanics to distribute keys. Post-quantum encryption algorithms are encryption methods that rely on mathematical challenges that quantum computers cannot solve quickly to ensure security. In this study, an integrated review of post-quantum encryption algorithms is conducted from the perspective of traditional cryptography. First, the concept and development background of post-quantum encryption are introduced. Then, the post-quantum encryption algorithm Kyber is studied. Finally, the achievements, difficulties and outstanding problems in this emerging field are summarized, and some predictions for the future are made.

Sdn-Based Detection and Mitigation of Ddos Attacks on Smart Homes

“…[58] proposed the Supersingular Isogeny Key Encapsulation (SIKE) algorithm for FPGA platforms, its relevance in the post-quantum cryptography landscape, and the importance of FPGA in cryptographic applications, particularly for IoT devices. [59] provided a broad overview of the transition to post-quantum security, identifying both opportunities and challenges that arise from this shift.…”
