        abstract = {Quantum computing poses a significant threat to traditional public-key cryptographic systems such as RSA and Elliptic Curve Cryptography, which are widely used for secure communication and digital licensing. Algorithms like Shor’s algorithm can theoretically break these classical systems once large-scale quantum computers become practical. This paper presents a comprehensive survey of quantum security and post-quantum cryptographic techniques with a focus on secure product key exchange systems. The study reviews lattice-based cryptographic schemes, particularly CRYSTALS-Kyber, and other Key Encapsulation Mechanisms such as NTRU, FrodoKEM, and SABER. Additionally, the paper discusses the motivation for hybrid cryptographic architectures that combine classical and post-quantum methods to ensure both current security and future quantum resistance. The survey highlights existing challenges, security implications, and practical considerations for deploying quantum-resistant key exchange systems in real-world applications such as digital licensing, authentication, and secure device communication.},
