Impact of Quantum Computing on Cryptography: Tracing Progress, Identifying Challenges, and Safeguarding Information in the Quantum Era
Jitendra Kurmi, Vipin Rawat, Km Divya · 2024
Cryptography and security are experiencing a period of profound change due to the potential for scalable quantum computing. Here we take a look back at how far we’ve come in our quest to make large-scale quantum computing a reality. We also provide a brief overview of the current cryptographic primitives and the dangers they face. New cryptographic primitives, known as post-quantum cryptography (PQC), are being standardized in an attempt to overcome these difficulties. We talk about the mathematical issues that characterize various types of PQC candidates and how they can withstand an attack from a hostile party with access to a powerful quantum computer. This line of inquiry has occurred with the porting of numerous conventional cryptography primitives to the quantum realm. This is the setting in which we talk about TRNG, Physically Enclosable Function, and Quantum Key Distribution (QKD). We get a sneak peek at the implementation-related vulnerabilities that result from such implementations.
