Ariadne – A Rust implementation of aperiodic cryptography [Developer Tools]
39 points, 31 comments
A Rust implementation of aperiodic cryptography using a dynamic, history-dependent cryptographic model.
- Uses a "Cryptographic Virtual Machine" with an implicit, emergent cryptographic path
- Features a large, deterministically-generated binary tree of cryptographic rounds ("Labyrinth")
- Employs a secret path ("Thread") rediscovered per data block via keyed hashing
- Ensures aperiodic operation by ratcheting state forward, preventing repetition
- Provides inherent tamper evidence by breaking the thread if ciphertext is modified
- Released as experimental, unaudited alpha software under CC0 for public use
