Cryptography
This security thread follows cryptography through original research, public projects, and source reports. Read the evidence below to see which developments are represented in SYMTRI’s archive.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗44 classified signals in the fourteen-day window. These counts include signals awaiting readable evidence.
Recent sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Show HN: Collaborative money tracker, E2E encryption, MCP ↗
Hi HN, I'm Andrei. I built a money tracker for myself with everything I ever wanted from one. What was important for me is wallets in different currencies (I travel a lot), planning future payments, seeing what balances would look like at certain date in the future and having external API and MCP. I had plans of maybe making it public one day so I decided to encrypt amounts and balances to stand out from gazillion of other trackers, then I kept a…

Anyone built something where AI computation get cryptography receipts ↗
We're a small proof-of-useful-work project. The validators don't mine — they verify AI computations (matrix multiplications + activation functions) and get consensus weight for it. The part that matters to you: submit any GEMM workload up to 256×256 and we return the result plus a cryptographic receipt — a SHA-256 commitment chain folded into our ledger state, verifiable by anyone forever. Free, no token, no signup beyond an API key we generate i…

Prompt-Segmentation Meets ROI Encryption: Fine-Grained Video Protection Based on Diffusion Isolation ↗
Region-of-interest (ROI) selective encryption in H.265/HEVC aims to protect sensitive content while preserving the utility of non-ROI regions. Existing coding-unit (CU)-level approaches still suffer from substantial encryption redundancy for two reasons. First, existing approaches map object-detection bounding boxes to CUs, producing regular rectangular regions, which poorly match the shape of irregular ROI boundaries, such as facial contours. Second, their coding-tree-unit (CTU)-based diffusion isolation expands the protected footprint in fixed $64\times64$ blocks, causing encryption-induced…

Mspep – Encryption from physical sensor entropy (defensive publication) ↗
I’m the inventor. MSPEP fuses multiple physical sensors already present on any device — magnetometer, thermistors, accelerometer, microphone, RF front-end, port timing — into a hardware-rooted entropy pool for cryptographic key generation. Released today as a defensive publication to establish prior art (original concept June 27, 2026). 23 claims across 6 families including AI session security with continuous physical anomaly monitoring. No new h…

Dynamic Parameter Selection for CKKS Fully Homomorphic Encryption and Its RNS Variant ↗
In recent years, the Cheon–Kim–Kim–Song (CKKS) scheme has gained widespread popularity among practitioners due to its support for approximate arithmetic on encrypted data. However, the decrypted outputs of CKKS inherently contain approximation errors arising from homomorphic operations. If the error term in the ciphertext grows too large, the decrypted results may no longer satisfy the required precision or correctness. To mitigate this issue, error analysis and parameter selection must be performed in advance. Nevertheless, deriving tight error bounds and selecting efficient parameters while…

How to assess evidence about Cryptography
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
