A Constant-time AVX2 Implementation of a Variant of ROLLO
Transactions on Cryptographic Hardware and Embedded Systems, 2021 This paper introduces a key encapsulation mechanism ROLLO+ and presents a constant-time AVX2 implementation of it. ROLLO+ is a variant of ROLLO-I targeting IND-CPA security. The main difference between ROLLO+ and ROLLO-I is that the decoding algorithm of

On the Performance and Security of Multiplication in GF(2N)
Cryptography, 2018 Multiplications in G F ( 2 N ) can be securely optimized for cryptographic applications when the integer N is small and does not match machine words (i.e., N < 32 ).

Single-Trace Attacks on Message Encoding in Lattice-Based KEMs
IEEE Access, 2020 In this article, we propose single-trace side-channel attacks against lattice-based key encapsulation mechanisms (KEMs) that are the third-round candidates of the national institute of standards and technology (NIST) standardization project. Specifically,

A Prototype for evaluating Post-Quantum Cryptography on resource-constrained Hardware with real-world Smart City Sensor Data [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesAs the threat of quantum computing to classical cryptography grows, the transition to post-quantum cryptographic (PQC) systems becomes essential—particularly for smart city infrastructures that rely heavily on secure, real-time sensor data.

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 ...

Cache-Timing Attack Against HQC
Transactions on Cryptographic Hardware and Embedded Systems, 2023 In this paper, we present the first chosen-ciphertext (CC) cache-timing attacks on the reference implementation of HQC. We build a cache-timing based distinguisher for implementing a plaintext-checking (PC) oracle.
