Verified NTT Multiplications for NISTPQC KEM Lattice Finalists: Kyber, SABER, and NTRU
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Postquantum cryptography requires a different set of arithmetic routines from traditional public-key cryptography such as elliptic curves. In particular, in each of the lattice-based NISTPQC Key Establishment finalists, every state-ofthe-art optimized ...

Multi-Parameter Support with NTTs for NTRU and NTRU Prime on Cortex-M4
Transactions on Cryptographic Hardware and Embedded Systems, 2022 We propose NTT implementations with each supporting at least one parameter of NTRU and one parameter of NTRU Prime. Our implementations are based on size-1440, size-1536, and size-1728 convolutions without algebraic assumptions on the target polynomial ...

MAYO: Practical Post-Quantum Signatures from Oil-and-Vinegar Maps [PDF]
, 2022 The Oil and Vinegar signature scheme, proposed in 1997 by Patarin, is one of the oldest and best understood multivariate quadratic signature schemes. It has excellent performance and signature sizes but suffers from large key sizes on the order of 50 KB,

HILA5 pindakaas: on the CCA security of lattice-based encryption with error correction
, 2018 We show that the NISTPQC submission HILA5 is not secure against chosen-ciphertext attacks. Specifically, we demonstrate a key-recovery attack on HILA5 using an active attack on reused keys. The attack works around the error correction in HILA5.
