Looking for encrypted object formats
I'm looking for prior art in encrypted object formats intended for encryption at rest (or store and forward messaging) for objects in the kilobytes to gigabytes range. Most probably involve marshalling together some symmetrically encrypted data along with a metadata block that includes details on key management and transports the …
The best visual representations of elliptic curves on finite fields you are aware of
Hi guys, in few words: my head wraps around visual representations way way way easier than math math models and watching visual presentations (better if they are interactive) makes my knowledge more flexible. I'm aware of the representation of the curve on the Real filed, it is very clear of …
Storing libsodium private keys on disk
Hi everyone, I want to use libsodium in PHP in a little code signing/verifying library I'm writing. I had a working implementation in OpenSSL, but that extension isn't always installed on hosts, where it seems that libsodium mostly is. The API seems pretty straightforward, with one exception - how does …
Excited to share my latest research in Privacy Preserving Authentication technology!
🌟 **Dear Scientists, Researchers, Scholars, and Enthusiasts,** 🌟 I am **thrilled** to announce the pre-print of my latest research paper, now available on the [International Association for Cryptologic Research (IACR) ePrint archive](https://eprint.iacr.org/2024/2066). 📚✨ >**Goal**: To authenticate accurately and securely **without revealing both virtual public identifiers** (e.g., usernames, user IDs) **and …
What’s the Best Stock Screener for “Point-in-Time” Historical Data?
I’m looking for a stock screener that allows for point-in-time filtering—meaning I can select a past date and screen stocks based on their data as it was on that date (rather than adjusted or restated figures). I want to use this to validate and backtest my current stock-picking strategy by …
No direction, no rudder, no sail, nothing.
This is the worst environment to trade in! No direction, so we have no inclination what direction the market is headed. Can't go long, because Trump will go on a geopolitical tirade during market hours a cause a selloff. Can't short, because at some point bad news= good news or …
A mnemonic system to (almost) effortlessly memorize 128-bit of entropy
Hi, I am working on a decentralized digital identity management system, and I would like to ask for a wider community feedback. In my opinion one of the biggest issues with decentralized identity management systems is the problem of the long lived private key loss or compromise. I am designing …
So this is my latest research pre-print, short digital signatures from the non-abelian hidden subgroup problem using a non-commutative bilinear matrix platform and information theory to equivocate intermediate entropy.
Since we're sharing our pre-prints, this is my latest research. The use case is low communication overhead digital signatures, good for constrained network environments. I was researching novel lattice constructions and one idea simply led to the next. Everyone forgot non-commutative cryptography was a thing after braid groups, but the …
CA root attack
What's a good paper on CA root attacks? You know, if the signing chain was compromised; what is there in place to mitigate that?
