A Quantum-Secure Niederreiter Cryptosystem using Quasi-Cyclic Codes

This work addresses the need for quantum-resistant cryptography, offering a practical solution with specific performance gains, though it appears incremental as it builds on existing Niederreiter frameworks.

The paper tackled the problem of designing a quantum-secure cryptosystem by proposing a new Niederreiter cryptosystem based on quasi-cyclic codes, resulting in improved transmission rate and smaller keys compared to existing methods using binary Goppa codes.
