Introduction HQC (H amming Q uasi- C yclic) is a code-based Key Encapsulation Mechanism (KEM) whose security is based on the hardness of solving the Quasi-Cyclic Syndrome …

Apr 10, 2024 · We thank the community for their support in trying to improve the security of HQC for side channel attacks and for improvements on hardware implementations of HQC.

Mar 11, 2025 · With HQC in the toolkit, organizations will soon have two independent encryption algorithms (one lattice-based, one code-based) to choose from – or even deploy in tandem for …

Mar 12, 2025 · Post-quantum cryptographic implementation of HQC (Hamming Quasi-Cyclic) - a NIST PQC candidate for quantum-resistant key encapsulation using code-based cryptography.

Mar 14, 2025 · HQC is built upon the Quasi-Cyclic Moderate Density Parity-Check (QC-MDPC) code structure, which allows it to balance security, performance, and key size more effectively …

This article presents a technical and educational review of the HQC (Hamming Quasi-Cyclic) algorithm, recently standardized by NIST as a post-quantum encryption scheme.

Jan 5, 2025 · Of particular relevance to our work, HQC is based on quasi-cyclic codes, which are codes generated by matrices consisting of two cyclic blocks.

Mar 11, 2025 · NIST then moved to define a 4th round, and which assessed BIKE, Classic McEliece, HQC and SIKE. HQC and BIKE have similar performance levels, and both are code …

Mar 11, 2025 · NIST has chosen a new algorithm for post-quantum encryption called HQC, which will serve as a backup for ML-KEM, the main algorithm for general encryption. HQC is based …

Mar 27, 2025 · "We began developing HQC in the 2000s, and by the 2010s, we had demonstrated that this protocol resolved a 40-year-old open problem in code-based key …
