Beyond Scalar Probes: Exploiting Vector-Valued Outputs in ReLU Networks For Signature Extraction
Gorka Abad, Claude Carlet, Ermes Franch +2
We revisit cryptanalytic extraction of ReLU networks from a geometric and algebraic perspective. Rather than restricting attention to a single output component, we study the full v…
Decoding Desarguesian spread codes beyond half minimum distance
Ermes Franch, Chunlei Li, Angelica Piccirillo
Spread codes are a well-known family of constant-dimension subspace-metric codes. For constant dimension and ambient space dimension being a multiple of , these codes ha…
Removing the Trigger, Not the Backdoor: Alternative Triggers and Latent Backdoors
Gorka Abad, Ermes Franch, Stefanos Koffas +1
Current backdoor defenses assume that neutralizing a known trigger removes the backdoor. We show this trigger-centric view is incomplete: \emph{alternative triggers}, patterns perc…
NegaBent, No Regrets: Evolving Spectrally Flat Boolean Functions
Claude Carlet, Marko Ðurasevic, Ermes Franch +3
Negabent Boolean functions are defined by having a flat magnitude spectrum under the nega-Hadamard transform. They exist in both even and odd dimensions, and the subclass of functi…
NoMod: A Non-modular Attack on Module Learning With Errors
Cristian Bassotto, Ermes Franch, Marina Krček +1
The advent of quantum computing threatens classical public-key cryptography, motivating NIST's adoption of post-quantum schemes such as those based on the Module Learning With Erro…
Bounded-degree Low Rank Parity Check Codes
Ermes Franch, Chunlei Li
Low-rank parity-check (LRPC) codes are the rank-metric analogue of low-density parity-check codes and they found important applications in code-based cryptography. In this paper we…
Two new algorithms for error support recovery of low rank parity check codes
Ermes Franch, Chunlei Li
Due to their weak algebraic structure, low rank parity check (LRPC) codes have been employed in several post-quantum cryptographic schemes. In this paper we propose new improved de…
Generalized LRPC codes
Ermes Franch, Philippe Gaborit, Chunlei Li
In this paper we generalize the notion of low-rank parity check (LRPC) codes by introducing a bilinear product over F^m q based on a generic 3-tensor in Fq^mxmxm, where Fq is the f…
Low Row Rank Parity Check Codes
Ermes Franch, Chunlei Li
In this paper we present an extended variant of low rank parity check matrix (LRPC) codes that have received significant interests in recent years. It is shown that the extension i…
