Exploiting Load/Store Leakage of Sparse Vectors for Key Recovery in HQC
Gustavo Banegas, Benjamin Smith, Jad Zahreddine
Hamming Quasi-Cyclic (HQC) is a code-based key encapsulation mechanism selected by NIST for standardization, making its resistance to implementation attacks critically important. W…
Low-Stack HAETAE for Memory-Constrained Microcontrollers
Gustavo Banegas, Kim Youngbeom, Seo Seog Chung +1
We present a low-stack implementation of the module-lattice signature scheme HAETAE, targeting microcontrollers with 8 kB-16 kB of available SRAM. On such devices, peak stack usage…
A Fault Analysis on SNOVA
Gustavo Banegas, Ricardo Villanueva-Polanco
SNOVA is a post-quantum cryptographic signature scheme known for its efficiency and compact key sizes, making it a second-round candidate in the NIST post-quantum cryptography stan…
Hardened CTIDH: Dummy-Free and Deterministic CTIDH
Gustavo Banegas, Andreas Hellenbrand, Matheus Saldanha
Isogeny-based cryptography has emerged as a promising postquantum alternative, with CSIDH and its constant-time variants CTIDH and dCTIDH offering efficient group-action protocols.…
Compressed verification for post-quantum signatures with long-term public keys
Gustavo Banegas, Anaëlle Le Dévéhat, Benjamin Smith
Many signature applications-such as root certificates, secure software updates, and authentication protocols-involve long-lived public keys that are transferred or installed once a…
Fast and Frobenius: Rational Isogeny Evaluation over Finite Fields
Gustavo Banegas, Valerie Gilchrist, Anaëlle Le Dévéhat +1
Consider the problem of efficiently evaluating isogenies of elliptic curves over a finite field , where the kernel is a cyclic g…
On recovering block cipher secret keys in the cold boot attack setting
Gustavo Banegas, Ricardo Villanueva-Polanco
This paper presents a general strategy to recover a block cipher secret key in the cold boot attack setting. More precisely, we propose a key-recovery method that combines key enum…
Wavelet: Code-based postquantum signatures with fast verification on microcontrollers
Gustavo Banegas, Thomas Debris-Alazard, Milena Nedeljković +1
This work presents the first full implementation of Wave, a postquantum code-based signature scheme. We define Wavelet, a concrete Wave scheme at the 128-bit classical security lev…
Quantum-Resistant Security for Software Updates on Low-power Networked Embedded Devices
Gustavo Banegas, Koen Zandberg, Adrian Herrmann +2
As the Internet of Things (IoT) rolls out today to devices whose lifetime may well exceed a decade, conservative threat models should consider attackers with access to quantum comp…
A new class of irreducible pentanomials for polynomial based multipliers in binary fields
Gustavo Banegas, Ricardo Custodio, Daniel Panario
We introduce a new class of irreducible pentanomials over of the form . Let and use to define the finite fiel…
