Title: Engineering Practical Rank-Code-Based Cryptographic Schemes on Embedded Hardware. A Case Study on ROLLO
In this paper, we investigate the practical performance of rank-code based cryptography on FPGA platforms by presenting a case study on the quantum-safe KEM scheme based on LRPC codes called ROLLO, which was among NIST post-quantum cryptography standardization round-2 candidates. Specifically, we present an FPGA implementation of the encapsulation and decapsulation operations of the ROLLO KEM scheme with some variations to the original specification. The design is fully parameterized, using code-generation scripts to support a wide range of parameter choices for security levels specified in ROLLO. At the core of the ROLLO hardware, we presented a generic approach for hardware-based Gaussian elimination, which can process both non-singular and singular matrices. Previous works on hardware-based Gaussian elimination can only process non-singular ones. However, a plethora of cryptosystems, for instance, quantum-safe key encapsulation mechanisms based on rank-metric codes, ROLLO and RQC, which are among NIST post-quantum cryptography standardization round-2 candidates, require performing Gaussian elimination for random matrices regardless of the singularity. To the best of our knowledge, this work is the first hardware implementation for rank-code-based cryptographic schemes. The experimental results suggest rank-code-based schemes can be highly efficient.  more » « less

    In this paper, we investigate the possibility of performing Gaussian elimination for arbitrary binary matrices on hardware. In particular, we presented a generic approach for hardware-based Gaussian elimination, which is able to process both non-singular and singular matrices. Previous works on hardware-based Gaussian elimination can only process non-singular ones. However, a plethora of cryptosystems, for instance, quantum-safe key encapsulation mechanisms based on rank-metric codes, ROLLO and RQC, which are among NIST post-quantum cryptography standardization round-2 candidates, require performing Gaussian elimination for random matrices regardless of the singularity. We accordingly implemented an optimized and parameterized Gaussian eliminator for (singular) matrices over binary fields, making the intense computation of linear algebra feasible and efficient on hardware. To the best of our knowledge, this work solves for the first time eliminating a singular matrix on reconfigurable hardware and also describes the a generic hardware architecture for rank-code based cryptographic schemes. The experimental results suggest hardware-based Gaussian elimination can be done in linear time regardless of the matrix type.

    BIKE is a code-based Key Encapsulation Mechanism (KEM) currently under consideration for standardization by the National Institute of Standards and Technology (NIST). BIKE, along with several other candidates, is being evaluated in the fourth round of the NIST Post-Quantum Cryptography (PQC) competition. In comparison to the lattice-based candidates, relatively little effort has been focused on analyzing this algorithm for side-channel vulnerabilities, especially in hardware. There have been several works on side-channel attacks and countermeasures on software implementations of BIKE, but as of yet, there have been no works focused on hardware. This work presents the first side-channel attack on a hardware implementation of BIKE. The attack targets a public implementation of the algorithm and is able to fully recover the long-term secret key with only several dozen traces. This work reveals BIKE’s significant susceptibilities to side-channel attacks when implemented in hardware and the need for investigation of hardware countermeasures.

    The rapid advancement in quantum technology has initiated a new round of exploration of efficient implementation of post-quantum cryptography (PQC) on hardware platforms. Key encapsulation mechanism (KEM) Saber, a module lattice-based PQC, is one of the four encryption scheme finalists in the third-round National Institute of Standards and Technology (NIST) standardization process. In this paper, we propose a novel Toeplitz Matrix-Vector Product (TMVP)-based design strategy to efficiently implement polynomial multiplication (essential arithmetic operation) for KEM Saber. The proposed work consists of three layers of interdependent efforts: (i) first of all, we have formulated the polynomial multiplication of KEM Saber into a desired mathematical form for further developing into the proposed TMVP-based algorithm for high-performance operation; (ii) then, we have followed the proposed TMVP-based algorithm to innovatively transfer the derived algorithm into a unified polynomial multiplication structure (fits all security ranks) with the help of a series of algorithm-to-architecture co-implementation/mapping techniques; (iii) finally, detailed implementation results and complexity analysis have confirmed the efficiency of the proposed TMVP design strategy. Specifically, the field-programmable gate array (FPGA) implementation results show that the proposed design has at least less 30.92% area-delay product (ADP) than the competing ones.

    In 2022, NIST selected the first set of four post-quantum cryptography schemes for near-term standardization. Three of them - CRYSTALS-Kyber, CRYSTALS-Dilithium, and FALCON - belong to the lattice-based family and one - SPHINCS+ - to the hash-based family. NIST has also announced an ”on-ramp” for new digital signature candidates to add greater diversity to the suite of new standards. One promising set of schemes - a subfamily of code-based cryptography - is based on the linear code equivalence problem. This well-studied problem can be used to design flexible and efficient digital signature schemes. One of these schemes, LESS, was submitted to the NIST standardization process in June 2023. In this work, we present a high-performance hardware implementation of LESS targeting Xilinx FPGAs. The obtained results are compared with those for the state-of-the-art hardware implementations of CRYSTALS-Dilithium, SPHINCS+, and FALCON.

    Recent advances in quantum computing have initiated a new round of cryptosystem innovation as the existing public-key cryptosystems are proven to be vulnerable to quantum attacks. Several types of cryptographic algorithms have been proposed for possible post-quantum cryptography (PQC) candidates and the lattice-based key encapsulation mechanism (KEM) Saber is one of the most promising algorithms. Noticing that the polynomial multiplication over ring is the key arithmetic operation of KEM Saber, in this paper, we propose a novel strategy for efficient implementation of polynomial multiplication on the hardware platform. First of all, we present the proposed mathematical derivation process for polynomial multiplication. Then, the proposed hardware structure is provided. Finally, field-programmable gate array (FPGA) based implementation results are obtained, and it is shown that the proposed design has better performance than the existing ones. The proposed polynomial multiplication can be further deployed to construct efficient hardware cryptoprocessors for KEM Saber.
