RejSCore: Rejection Sampling Core for Multivariate-Based Public Key Cryptography

Post-quantum multivariate public key cryptography MPKC schemes resist quantum threats but require heavy operations, such as rejection sampling, which challenge resource-limited devices. Prior hardware designs have addressed various aspects of MPKC signature generation. However, rejection sampling...

AMD Kintex 7-Series FPGA和AMD Artix 7-Series FPGA 安全漏洞

The AMD Kintex 7-Series FPGA and AMD Artix 7-Series FPGA are both FPGA chips from UltraMicroelectronics AMD. A security vulnerability exists in AMD Kintex 7-Series FPGAs and AMD Artix 7-Series FPGAs that stems from insufficient voltage and clock burr protection, which could lead to an attacker...

Undervoltage-based Static Side-channel Attacks (“Chypnosis”) on FPGAs

Summary This document describes a potential attack technique against FPGA devices that leverages side-channel analysis SCA techniques to physically extract register and memory content from the device. In applications following best practices for security, critical data, such as decryption keys, i...

Lightweight Fault Detection Architecture for NTT on FPGA

Post-Quantum Cryptographic PQC algorithms are mathematically secure and resistant to quantum attacks but can still leak sensitive information in hardware implementations due to natural faults or intentional fault injections. The intent fault injection in side-channel attacks reduces the reliabili...

Energy-Efficient NTT Sampler for Kyber Benchmarked on FPGA

Kyber is a lattice-based key encapsulation mechanism selected for standardization by the NIST Post-Quantum Cryptography PQC project. A critical component of Kyber's key generation process is the sampling of matrix elements from a uniform distribution over the ring Rq . This step is one of the mos...
