Bitstream Fault Injection Attacks on CRYSTALS Kyber Implementations on FPGAs

2024 Design, Automation & Test in Europe Conference & Exhibition (DATE)
CRYSTALS-Kyber is the only Public-key Encryption (PKE)/ Key-encapsulation Mechanism (KEM) scheme that was chosen for standardization by the National Institute of Standards and Technology initiated Post-quantum Cryptography competition (so called NIST PQC). In this paper, we show the first successfully malicious modifications of the bitstream of a Kyber

Improved Correlation Power Analysis Attack on the Latest Cortex M4 Kyber Implementation

Cryptography
CRYSTALS-Kyber has been standardized as a general public-key post-quantum algorithm under the name of ML-KEM after NIST released its first three final post-quantum standards in August 2024.

Probabilistic modeling of decryption-failure bounds in CRYSTALS-Kyber under the post-quantum threat model

Machine Learning: Science and Technology
We present a probabilistic modeling framework for quantifying decryption-failure probability (DFP) in CRYSTALS–Kyber , the lattice-based key encapsulation mechanism standardized by National Institute of Standards and Technology as module-lattice-based ...

A Pipelined Hardware Design of FNTT and INTT of CRYSTALS-Kyber PQC Algorithm

Information
Lattice-based post-quantum cryptography (PQC) algorithms demand number theoretic transform (NTT)-based polynomial multiplications. NTT-based polynomials’ multiplication relies on the computation of forward number theoretic transform (FNTT) and inverse ...

Quantum-Safe Threshold Cryptography for Decentralized Group Key Management via Dealerless DKG (CRYSTALS–Kyber)

Mathematics
Post-quantum threshold cryptography requires complete elimination of classical assumptions to achieve genuine quantum resistance. This work presents a fully lattice-based dealerless distributed key generation (DKG) protocol with threshold CRYSTALS–Kyber ...

Some Mathematical Problems Behind Lattice-Based Cryptography

Cryptography
In 1994, P. Shor discovered quantum algorithms that can break both the RSA cryptosystem and the ElGamal cryptosystem. In 2007, D-Wave demonstrated the first quantum computer.
