Optimizing BIKE for the Intel Haswell and ARM Cortex-M4
Transactions on Cryptographic Hardware and Embedded Systems, 2021 BIKE is a key encapsulation mechanism that entered the third round of the NIST post-quantum cryptography standardization process. This paper presents two constant-time implementations for BIKE, one tailored for the Intel Haswell and one tailored for the ...

Classic McEliece on the ARM Cortex-M4
Transactions on Cryptographic Hardware and Embedded Systems, 2021 This paper presents a constant-time implementation of Classic McEliece for ARM Cortex-M4. Specifically, our target platform is stm32f4-Discovery, a development board on which the amount of SRAM is not even large enough to hold the public key of the ...

Efficient Implementation of SPEEDY Block Cipher on Cortex-M3 and RISC-V Microcontrollers
Mathematics, 2022 The SPEEDY block cipher family announced at the CHES 2021 shows excellent performance on hardware architectures. Due to the nature of the hardware-friendly design of SPEEDY, the algorithm has low performance for software implementations. In particular, 6-

Efficient Hardware Implementation of Constant Time Sampling for HQC
CoRR, 2023 HQC is one of the code-based finalists in the last round of the NIST post quantum cryptography standardization process. In this process, security and implementation efficiency are key metrics for the selection of the candidates. A critical compute kernel with respect to efficient hardware implementations and security in HQC is the sampling method used ...

Number-Theoretic Transform with Constant Time Computation for Embedded Post-Quantum Cryptography
Acta Electrotechnica et Informatica, 2022 In this article, we describe the principles and advantages of using the Number-Theoretic Transform (NTT) in post-quantum cryptography. We deal with usages of NTT in post-quantum algorithms included in the competition announced by the National Institute ...

Output-sensitive Information flow analysis [PDF]
Logical Methods in Computer Science, 2021 Constant-time programming is a countermeasure to prevent cache based attacks where programs should not perform memory accesses that depend on secrets. In some cases this policy can be safely relaxed if one can prove that the program does not leak more ...

Finding Small and Large
IEEE Transactions on Quantum Engineering, 2020 Algorithms for triangle finding, the smallest nontrivial instance of the k-clique problem, have been proposed for quantum computers. Still, those algorithms assume the use of fixed access time quantum RAM.
