Leveraging LDPC-Optimized Niederreiter Cryptosystems for Quantum-Resilient IoT Security Applications

The Niederreiter Cryptosystem is a well-established post-quantum cryptographic scheme knownfor its security, yet it suffers from large key sizes and computational inefficiencies, making it lesssuitable for resource-constrained environments like the Internet of Things (IoT) and large-scale communications. This paper presents an enhanced version of the Niederreiter Cryptosystem by integrating Low-Density Parity-Check (LDPC) codes, a class of error-correcting codes characterized by sparse matrices that enable efficient decoding. By leveraging the structural advantages of LDPC codes, the proposed system achieves significant reductions in key sizes and improves decoding efficiency while maintaining strong quantum resistance. We propose an innovative optimization of the Niederreiter cryptosystem by integrating Low-Density Parity-Check (LDPC) codes to achieve enhanced decoding efficiency and reduced key sizes. Our contributions include a novel encoding decoding mechanism, an in-depth security analysis, and implementation results demonstrating reduced computational overhead and improved practicality in post-quantum cryptography. The main contributions of this work include: (1) a novel method for integrating LDPC codes into the Niederreiter framework, leading to a more compact cryptographic scheme; (2) a detailed analysis of the key size reductions and performance gains offered by LDPC codes; and (3) an evaluation of the optimized system’s suitability for IoT applications and large-scale communication networks. Simulation results demonstrate that the proposed LDPC-enhanced Niederreiter Cryptosystem provides a significant improvement in resource efficiency and scalability without compromising security. This optimization makes it a viable candidate for secure post-quantum cryptography in future communication systems.
