Application-Specific Optimization of Hybrid Post-Quantum Cryptographic Frameworks in Resource-Constrained Environments
Аннотация
the rapid advancement of quantum computing introduces substantial risks to classical cryptographic algorithms that rely on number-theoretic problems, such as the Rivest–Shamir–Adleman algorithm and elliptic curve cryptography. These cryptographic primitives are susceptible to polynomial-time quantum algorithms like those proposed by Shor and Grover, thereby endangering the security of contemporary digital infrastructures. In light of these emerging threats, the global cryptographic community is prioritizing the development and deployment of quantum-resistant cryptographic techniques. These include diverse algorithmic families such as those based on lattices, hash functions, error-correcting codes, and multivariate polynomials. Each approach exhibits distinct trade-offs in terms of computational performance, key length, signature size, and long-term resilience. This paper introduces a hybrid cryptographic framework optimized for specific application domains, particularly those with limited computational and energy resources. The proposed architecture strategically combines lattice-based encryption, hash-based digital signatures, and code-based key encapsulation mechanisms to form a unified model for secure data transmission. The architecture is implemented and evaluated across heterogeneous computing environments, including low-power embedded systems and Field-Programmable Gate Arrays. Experimental metrics such as execution latency, computational overhead, memory consumption, and energy efficiency are assessed and benchmarked against traditional single-algorithm deployments. The findings demonstrate that the hybrid approach maintains strong quantum resistance while significantly reducing performance penalties, making it suitable for mobile platforms, Internet of Things environments, and real-time communication systems. Future work should emphasize further fine-tuning for specific industrial domains, standardization of hybrid cryptographic protocols, and integration with artificial intelligence-based adaptive security layers to ensure sustainability in the approaching quantum era.
