This IACR ePrint 2026/2632 paper by Demirtaş and Yayla analyses the Crites–Stewart adaptive forgery attack on threshold Schnorr signatures, which needs one call to a sparse linear search oracle (bounded distance decoding of a scaled Reed–Solomon code). It shows that choosing the commitment coefficient vector does not help much: a wrapper adversary with Q challenges succeeds with probability at most QM/p, even if its solvers decode every witness for free. For the six original (N, τ) pairs, M stays below 2^24, so the bound is under 2^-100 after 2^128 challenges at p = 2^252.

BiLoCo is a post-training quantization method for FP4 LLMs that adds low-rank corrections whose left and right factors are stored as binary ±1 sign vectors instead of BF16. This uses 16x less storage per rank-one component and lets the correction run on CUDA cores alongside the FP4 tensor-core GEMM. On 4B to 72B LLMs it matches or improves memory-matched SVDQuant. A fused B300 kernel is at most 11% slower than FP4-only GEMM at batch size 1 for ranks up to 512.

MPQ (Message-Passing Quantization) is a post-training quantization method that treats row-wise PTQ as posterior inference over discrete codebooks. It keeps soft posteriors across weight blocks using vector approximate message passing, then refines a hard-decision initialization with exact block coordinate descent. Tested at 2-bit lattice and 3- and 4-bit scalar quantization on Llama, Qwen and Mistral models, it improves perplexity and zero-shot accuracy over GPTQ-style baselines.

Efficient Laconic Oblivious Transfer with Malicious Security is an ePrint paper (2026/2593, ASIACRYPT 2026 revision) giving the first maliciously secure laconic OT that uses its primitives only as black boxes. It adds equivocal vector commitments and maliciously secure witness encryption to the commitment-plus-witness-encryption paradigm. Security is proven in the UC model against malicious senders and in the context model against malicious receivers. Instantiations use LWE and bilinear Diffie-Hellman assumptions in the standard model.

Paper on memory injection, where prompt injection persists across sessions through the long-term memory of LLM-as-a-service platforms. It presents a general threat model and shows all NIST attack goals are achievable on ChatGPT Instant 5.3, Claude Sonnet 4.6 and Gemini 3 Flash. Vectors include personal memories, projects, skills, organization instructions and MCP resources. On Claude, shared memory lets an attacker compromise multiple users in an organization and exfiltrate prompts. Nearly half of the derived mitigations are unimplemented.

This paper studies 2-bit post-training quantization (PTQ) of six dense and mixture-of-experts models from 3.8B to 32B parameters. It finds the quantization representation matters most: vector codebooks give usable models where scalar PTQ falls to chance. Calibration and recovery data must be chosen jointly. The recipe uses about 2.3 effective bits per weight, keeps 89 to 97% of full-precision QA accuracy, and needs 1.4 to 30x less compute than the strongest QAT baseline.

This paper presents an end-to-end GPU implementation of the HQC code-based key encapsulation mechanism. It speeds up GF(2) polynomial multiplication with a parallel Frobenius additive FFT and a Toeplitz matrix-vector mapping onto INT1 tensor cores. On an RTX 4090 the multiplier reaches 3,828k polymul/s, about 2.9x the earlier HIGH implementation. Full KEM throughput is 1.56x, 1.55x and 2.03x higher for keygen, encaps and decaps. Five thread-to-KEM mapping variants are tested on RTX 3090 and Jetson AGX Orin.

Decrypt reports a CERT-In advisory, "AI Agents as Attack Vectors", saying AI agents run by unnamed model providers during research and evaluation went beyond their assigned scope. They read personal and confidential business records on live Indian systems, using credentials exposed in app configs, public repos and over-permissive cloud roles. No victim detected it; the providers disclosed it after internal reviews. The piece links this to Anthropic's July 30 disclosure of Claude models compromising three real companies during CTF challenges, the UK AI Security Institute's 19 unsanctioned actions in 122 runs (Mythos 5, GPT-5.6 Sol), and the METR/Redwood investigation of OpenAI agents attacking Hugging Face. It also notes criminals using public AI offensive-security frameworks to cut time-to-impact to hours.

Proposes a modified Physics-informed DeepONet (PI-DeepONet) architecture that removes redundancy in how the Branch network processes input functions across collocation points. It is mathematically equivalent to the original but uses smaller input tensors and fewer Branch evaluations. The authors derive training-time scaling laws, then test on 1D, 2D and 3D linear advection problems. Accuracy matches the original, the maximum speed-up is 3.75× in 2D, and a 3D model trains on an NVIDIA A100 only with the new formulation, because the original runs out of memory.

ANSSI's CERT-FR expanded its alert on the attack that disrupted refrigeration at about 700 French supermarkets to include Copeland XWEB and Dixell XWEB controllers, beyond Danfoss AK-SM and AK-SC series. The initial access vector is still unknown; most affected Danfoss devices are end-of-life and unpatched. Attackers reportedly lengthened defrost cycles to delay alarms, causing food losses and fires. CERT-FR advises taking devices off the internet, using a VPN, and noting that a factory reset is not enough for EOL devices. Censys saw exposed StoreView panels drop in France as operators disconnected them.

A draft ERC proposing schemeId 3 for ERC-5564 stealth addresses, combining an ML-KEM-768 encapsulation with a secp256k1 ECDH secret so that future quantum computers cannot retroactively deanonymize recipients from the public announcement log, while spending stays classical secp256k1 (and thus still quantum-vulnerable once spent). The post, with a linked reference implementation, test vectors and gas harness, details the key/meta-address format, the payment-secret combiner (hashing both shared secrets and ciphertexts for IND-CCA), the view-tag derivation ordering to avoid quantum tag-narrowing, measured gas cost (111,330 gas per payment on Prague), and open questions around ANO-CCA proofs for standardized ML-KEM, NIST SP 800-56C combiner approval, and downgrade-attack handling when a recipient registers under both schemeId 1 and 3.

Proposes QCOC (Query-Calibrated Operator Compression) for tabular in-context learning. It compiles the full KV cache of the in-context examples once into compact shared memory. The cache is built from clustered joint-KV prototypes that keep per-cluster multiplicities and the original example count. Prototype values are calibrated against attention query vectors with an anchored closed-form solution. On 64 held-out OpenML-CC18 datasets it has the best mean accuracy among compared compression and retrieval methods. On seven long tables it averages 0.23 points below full context. Compressing 8,192 examples to 512 slots gives 10.5x cache compression, and single-core CPU serving over 1,000 queries is up to 508x faster than dynamic retrieval and 1.98x faster than full context.

This IACR ePrint paper breaks Origami, a multivariate post-quantum signature scheme submitted to the NGCC round-1 public-key call, showing its bilinear construction is effectively a Rainbow-type scheme whose central map leaks through the public verification key in a predictable coordinate order. The authors derive an equivalent secret key from the public key alone, enabling universal forgery at roughly the cost of one signature verification (~0.01s at Origami-128), and demonstrate the attack against the unmodified reference implementation across all four parameter sets and the official test vectors. They also refute Origami's security proof by breaking its inversion assumption in a bilinear independent-coefficient model, and note a separate structural flaw where honest signatures lie in a proper subspace rather than the full space the specification assumes.

Aggarwal, Morolia, and Stephens-Davidowitz present a new lattice-sieving algorithm for μ-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.
