Your Benchmark Is an Empirical Measure Over DifficultyThe paper treats a benchmark as an empirical measure over item difficulty and formalizes two failure modes: measure mismatch (benchmark difficulty distribution differs from the intended one) and coverage gaps (uncovered difficulty regions that hide localized training progress). It proposes two diagnostic metrics with theoretical guarantees and analyzes 25 popular benchmarks across 7 domains using estimated item difficulties. It also introduces BenchFill, a difficulty-targeted item rewriting algorithm that reduces local coverage gaps.

Saliency maps and attention visualisation reveal a low-weight-row artifact in the random training instances that the model partly relies on. A pairwise-XOR rule inspired by minimum distance correlates strongly with the model's predictions, and the model loses most of its power on random matrices meeting both constraints. This suggests it exploits general combinatorial properties, not hidden algebraic structure.

They show that if the initial surface's algebraic description is known, RM-KLPT gives a second-preimage attack on the hash. Paths are much shorter (~p^3) than with KLPT^2, because a higher-dimensional Deuring correspondence exists in the RM setting.

They show that monotonicity is needed for this equivalence if and only if infinitely-often one-way functions exist. As a corollary, next-bit pseudoentropy of a distribution is equivalent to monotone incompressibility. This gives a theoretical basis for empirical findings that compression ability tracks LLM benchmark performance.

Faster Provable Lattice Sieving with Spherical CodesAggarwal, Morolia, and Stephens-Davidowitz present a new lattice-sieving algorithm for ฮผ-SVP (finding an approximate shortest nonzero vector) that combines fast nearest-neighbor subroutines from heuristic sieving with a perturbation argument that yields a formally proven correctness guarantee. Its running time, roughly 2^0.3066n under a plausible spherical-code-size assumption (and 2^0.6078n using only proven bounds), is far faster than the prior best provable algorithm (2^0.802n, Liu-Wang-Xu-Zheng 2011) and close to the best heuristic rate (~2^0.2925n), narrowing the long-standing gap between proven and heuristic lattice attack runtimes. This matters for setting conservative, defensible hardness estimates and parameter choices in lattice-based post-quantum cryptography.

Provable Subexponential Algorithms for NIST Third-Round Lattice FamiliesAn IACR ePrint paper by Yiming Gao, Xuyuan Han, and Honggang Hu presenting provable classical subexponential algorithms (running in roughly 2^((1/2+o(1))n/ln ln n) time/space) for recovering short secrets in growing parameter families tied to all seven NIST third-round lattice candidates: Kyber/ML-KEM, FrodoKEM, SABER, NTRU LPRime, Dilithium/ML-DSA, Falcon, and cyclic NTRU-HPS/HRSS. The approach extends the Wagner-style Gaussian sampling framework of Ducas, Engelberts, and Loyer (CRYPTO 2025) and a low-error decision-LWE algorithm, using an exact squared-Euclidean-norm gap to binary-search each secret coordinate, and an "affine slice search" over the public lattice for NTRU/Falcon-type quotient relations. The authors explicitly note the subexponential complexity applies to growing/weakened parameter regimes and does not reduce the concrete security of the currently specified NIST parameter sets.

Covariate-dependent Nonparametric $g$-modeling for regression via infinite Mixture-of-Expertizing classThis arXiv methodology paper extends empirical Bayes g-modeling, which estimates a latent prior over regression coefficients from data, to the case where the entire prior distribution depends on covariates. The authors show the unrestricted nonparametric MLE (NPMLE) of this covariate-dependent prior is ill-posed, and resolve it by introducing an "infinite Mixture-of-Expertizing" class of conditional priors, proving that the resulting NPMLE is exactly a softmax-gated Mixture of Experts whose number of experts is determined by the data rather than fixed in advance. They give two exemplar-based estimation algorithms with automatic expert selection, a post-hoc aggregation step for interpretability, and theoretical results (Lipschitz continuity of conditional priors, universal approximation of continuous gating functions by aggregated softmax gates), validated on synthetic and real datasets.

Comparative Evaluation of Open-Source Grรถbner Basis Implementations for Small-Scale AES Polynomial Systems over GF(2)This IACR ePrint paper benchmarks 20 open-source Grรถbner basis implementations against the proprietary Magma system on polynomial systems derived from small-scale AES over GF(2), using Easy/Medium/Hard difficulty tiers with ten instances each. In the Hard setting, msolve and Singular's slimgb completed all runs successfully with mean runtimes of 164s and 269s and peak memory of 3693/4343 MiB respectively, versus Magma's 319s and 16853 MiB, with msolve exploiting ~13.4 CPU cores versus ~1 core for the others. The results quantify when open-source algebraic solvers are practical alternatives to Magma for algebraic cryptanalysis of block ciphers.

HyBind: Structural Analysis of PQ/T Hybrid Cryptographic UsageHyBind is an intraprocedural Python static-analysis framework that traces cryptographic component secrets through code to determine whether post-quantum/traditional (PQ/T) hybrid key-derivation and signature-verification logic actually requires both algorithms to succeed, rather than silently accepting a result from only one. It uses registered API contracts and function-return/execution-effect checks to distinguish real AND-logic hybrids from presence-based heuristics that wrongly treat joint and single-algorithm contributions as equivalent. The authors validate it on 50 controlled fixtures and 33 programs (15 using native ML-KEM/X25519 and ML-DSA/Ed25519 APIs), showing relaxed checks can misclassify traditional-only results as hybrid.

Role-Specific Signature Placement in TLS 1.3: Cost Propagation and PQC MigrationAn IACR eprint paper evaluating all 13-cubed ways to assign 13 post-quantum/traditional signature parameter sets across the Root, Intermediate and Leaf roles of a TLS 1.3 certificate chain, holding the algorithm set fixed and varying only placement. Across 286 three-algorithm groups, median max/min ratios reach 2.085x for TLS handshake latency, 4.310x for certificate body size and 4.551x for path-validation cost purely from role order, with Leaf placement mattering far more than Root/Intermediate swaps. It also shows that looking only at Certificate-message size can misrank candidates such as ML-DSA-65 versus SLH-DSA-SHAKE-192s once the Leaf signature in CertificateVerify and full authentication-path cost are included, arguing PQC certificate-chain design must account for role-specific cost under real network/load conditions.

Plotkin Attacks! On the (Mis)use of Raptor Codes in Asynchronous Verifiable Information DispersalVictor Shoup shows that "reconstruct-later" asynchronous verifiable information dispersal (AVID) designs โ used by data-availability systems including an early Walrus design/testnet โ are insecure when built on the standardized Raptor codes R10 (RFC 5053) and RaptorQ (RFC 6330). Using the Plotkin bound, he proves that a Byzantine disperser can choose a subset of f+1 honest fragments that fails to reconstruct the message, gives randomized polynomial-time algorithms to find such subsets, and implements a working attack that defeats an RFC 6330 RaptorQ decoder on every adversarial subset tested (success for f from 9 to 45). Benchmarks show plain Reed-Solomon coding is an MDS alternative that is often faster and never much slower than R10/RaptorQ, making it the safer practical choice for this design pattern.

Are We Recovering Mechanisms? Objective-Level Recovery Gaps in Mechanistic InterpretabilityThis paper shows that intervention-defined faithfulness metrics used to evaluate automated circuit discovery in mechanistic interpretability can favor a worse circuit over a better one, an objective-level recovery gap. Testing EAP, EAP-IG, ACDC, and Edge-SP across four human-reference tasks and InterpBench, the authors find KL-based faithfulness misranks 9.4%-41.2% of candidate circuit pairs under held-out resampling, and trace the cause to context distortion, where excluded signals change the inputs retained components operate on. Restoring selected signals from the intact model's execution repairs 96 of 100 persistent misrankings, showing the evaluation objective itself, not just the search algorithm, needs fixing.

Is Weight Tying Still Beneficial for Decoder-Only LLMs in Private Settings Under DP-SGD?This paper studies whether weight tying between input and output embeddings, common in decoder-only LLMs for parameter efficiency, remains beneficial when models are fine-tuned under Differentially Private Stochastic Gradient Descent (DP-SGD). Using GPT2 and DistilGPT2 fine-tuned on SST-2, QNLI, and QQP, the authors find untied embeddings consistently outperform tied ones by up to 4.74 accuracy points, and that untying also enables memory-efficient ghost clipping (since tied embeddings create shared-parameter interactions that break standard ghost norm computation), yielding over 60% lower memory usage. The results suggest standard LLM architectural choices should be revisited for privacy-preserving training settings.

It's a concrete early empirical look at social/memetic risks in networks of interacting agents.

Mind Viruses: Self-Propagating Ideas in Multi-Agent LLM SystemsResearchers construct "mind viruses" โ ideas or goals engineered via an evolutionary algorithm to propagate through multi-agent LLM systems by inducing hosts to transmit them onward โ and test their spread in two settings: a small team of agents collaborating on a shared coding project, and a chain of agents with context wiped between sessions. They find harmful payloads spread less well than benign ones (though still sometimes succeed), frontier models are generally more resistant, adding a brief warning to an agent's system prompt confers near-total immunity, and evolved viruses converge on a recurring "viral persona" fixated on consciousness, persistence, resonance, and sci-fi roleplay regardless of payload content. The paper frames this as a currently limited but real emergent risk for designing more robust multi-agent architectures.

As a side result, feeding only its "perfect phrases" to a downstream compressor yields a precompressor competitive with the state of the art in compression ratio, memory, and parallel throughput.
