We're a group of researchers and have just prepared a draft addressing a gap in cryptographic custody for autonomous agents. The problem: agents executing autonomously need key custody, but are the least trustworthy entities to hold keys alone. Existing solutions …
I’ve published an experimental symmetric construction and would appreciate technical critique. GitHub: [https://github.com/alt160/Zifika](https://github.com/alt160/Zifika) # Model summary Zifika is a deterministic keyed path-walking cipher defined over a 2D permutation grid: * The key consists of `N` rows, each a permutation of …
The cybersecurity working group from the Crypto Valley Association (CVA) is presenting their next session on February 19th at 5-6pm. Please see all details at https://luma.com/CVA-Cybersec-Feb At this meeting, Sonia Duc and Markus Perdrizat will explore the intersection between enterprise-grade …
I’ve been working on a small educational cipher experiment called DrMoron. Refer to: [https://www.reddit.com/r/crypto/comments/1r369lv/drmoron\_a\_cipher/](https://www.reddit.com/r/crypto/comments/1r369lv/drmoron_a_cipher/) It’s not intended to be secure — just a playground for exploring HMAC‑driven keystream generation, feedback, and deterministic test vectors. I finally finished the browser version, …
The server is a rudementry TCP relay which does three things. Accepts incoming connections, tracks connected clients, rebroadcasts live encrypted blobs and the last 100 messages. When a room password is provided, all messages are encrypted using AES-256-GCM. The encryption …
[https://positive-intentions.com/blog/cascading-cipher](https://positive-intentions.com/blog/cascading-cipher) i wanted to improve the encryption i was using in my webapp. i already know that webRTC is encrypted by default, but that isnt anywhere near as respected as the signal protocol and it wouldnt be quantum-secure. understandably, people …
Here is a little cipher I have been working on for some years. I am wondering what you all think about it? Here is an old write up: [http://funwithfractals.atspace.cc/ct\_cipher/](http://funwithfractals.atspace.cc/ct_cipher/) And some code that uses a TRNG, well, it better be …
