FrogBard-512: Design and Experimental Evaluation of a Four-Voice Permutation-Based Hash Function
Victor Duarte Melo
FrogBard-512 is an experimental 512-bit hash function based on a custom 2048-bit permutation organized as four 512-bit voices. The sequential mode uses a 1024-bit rate, a 1024-bit…
Exact Hidden Paths in Noisy High Dimensional Path Spaces
Victor Duarte Melo
We introduce a mathematical and cryptographic framework for exact recovery of noisy hidden paths in high dimensional discrete path spaces. The work is inspired by the path integral…
ECCFROG522PP: An Enhanced 522 bit Weierstrass Elliptic Curve
Victor Duarte Melo
This paper presents ECCFROG522PP, a 522-bit prime-field elliptic curve in short Weierstrass form, designed with a focus on deterministic generation and public reproducibility. The…
EVA: Efficient Reinforcement Learning for End-to-End Video Agent
Yaolun Zhang, Ruohui Wang, Jiahao Wang +6
Video understanding with multimodal large language models (MLLMs) remains challenging due to the long token sequences of videos, which contain extensive temporal dependencies and r…
Symfrog-512: High-Capacity Sponge-Based AEAD Cipher (1024-bit State)
Victor Duarte Melo
This submission includes a complete reference implementation together with deterministic test vectors and a reproducible benchmark suite. All source code, build instructions, and r…
KyFrog: A High-Security LWE-Based KEM Inspired by ML-KEM
Victor Duarte Melo, Willian J. Buchanan
KyFrog is a conservative Learning-with-Errors (LWE) key-encapsulation mechanism designed to explore an alternative operating point compared to schemes with relatively small public…
