Quantum-enhanced algorithms for real-time processing in cryptographic systems: A path towards post-quantum security

New technologies such as quantum computing present a major challenge to the current cryptographic systems; thus, quantum-resistant techniques are required. This work describes a new approach for adapting QE schemes to real-life IT security applications, giving a glimpse of the way to post-quantum security. Hence, the architecture proposed here incorporates classical and quantum methods to present a vast enhancement in speed and the stability of security. The system seeks to solve this problem using a hybrid quantum-classical computing strategy. It achieves a 470 percent performance improvement in latency while withstanding both classical and post-quantum attacks concurrently. Field experiments and numerous tests for the accuracy and practicability of the framework established its elasticity and robustness. This research suggests many directions for further research – improving the efficiency of merging quantum-classical users, studying the adaptive quantum algorithms issue, and employing machine learning technology for the identification of threats. The applicability of quantum-enhanced cryptographic processing in producing practical and commercially viable technology highlights the significant advances that have been made in guaranteeing the security of sensitive applications in the coming years, including commerce and appeals. The findings of this type of work can be helpful to the continuous process of establishing post-quantum cryptographic standards and increasing the use of quantum-safe technologies.
