Any known test primes for multi-round Miller-Rabin?
Hoping for a list of three or more known primes anywhere between 256 and 1024 bits known to survive three or more rounds of Miller-Rabin before no more rounds may be done. If the exact number of rounds might also be known, that would be great. But three at a …
One Step Ahead - security app - White Paper
Over a month ago we released the White Paper that explains how One Step Ahead works under the hood — the security architecture, Smart Split, all of it. Whether you're technical or not, it's worth a read! Give it a go if you find spare minute!
Blind signatures for account-less subscriptions with built-in abuse prevention (BSc thesis + implementation)
It's already two years old, but I figured it might be interesting for this sub: Subscriptions (think: Newspaper/Netflix/Spotify) normally tie every article you read or song you play to an account, which allows profiling you and selling that data to advertisers. For my BSc thesis I built an account-less version …
What are some good Discord servers for cryptography?
I'd like to discuss the details of my project to people and I'd like to try discord. What are some active discord servers I could ask about my project? In particular, I'd like my project details scrutinized. I'm creating a WhatsApp clone. It's hardly unique, but I'd like to discuss …
A unified post-quantum framework: KEM and Signature schemes via Module-SIS
I am releasing the technical drafts and reference implementations for a unified post-quantum paradigm. Both the Key Encapsulation Mechanism (KEM) and the Digital Signature scheme are derived from the same underlying module-lattice structure, simplifying security assumptions and parameter management. Both primitives rely on the hardness of the module-SIS problem and …
What are the state of the art FHE libraries for ML/AI in 2026?
It is generally agreed upon that FHE and more generally, PETs, for ML/AI is going to be pretty slow. Despite that, there have been many libraries and attempts over the past decade to make these technologies more practical. Some of the biggest libraries in this area are [TF-Encrypted](https://github.com/tf-encrypted/tf-encrypted) and [Concrete-ML](https://github.com/zama-ai/concrete-ml). …
Fields and Groups in Cryptography
Hello folks, I am pretty new to cryptography and wanted to understand why particularly most of the schemes are being operated inside a field or a group ?? Why did that thought arrive while making the scheme ???
