PROJECTS
O1-EITE
CURRENT MAIN PROJECT
Everlasting Information-Theoretic Encryption on a Streaming State-Space Substrate

Development and formal verification of an authenticated encryption scheme with three security profiles: standardized post-quantum key exchange (A), a clocked key ratchet with provable erasure — past epochs stay sealed even after later state compromise (B), and post-session information-theoretic confidentiality against unbounded computational power (C). The state-space lineage, the cryptanalytic substrate, and the 2026 conference papers below all converge here.

MODEL LINEAGE
GSSM·Paper

The substrate — geometric state-space models: bounded hyperbolic recurrence with key-conditioned holographic recall.

→
O1

The stream — consumes unbounded input at constant memory, stays awake through silence, consults an external .causal knowledge index at runtime.

→
o1-state·Paper

The organism — surprise-gated plasticity, dosed sleep, live cross-architecture migration. Mamba, S5 and LRU fall out of one kernel operator.

CRYPTANALYTIC SUBSTRATE
dotcausal→live-casi→f8→f8-causal-cryptanalysis→fullround-key-recovery→Cryptanalytic-Memory-Lab

Knowledge format → live structural analysis → full-round distinguishers → causal readers → key recovery → bounded-state memory. The yield so far: full-round distinguishers on 11 ciphers.

FAQ
What is O1-EITE?
Authenticated encryption with three security profiles — standardized post-quantum key exchange (A), a clocked key ratchet with provable erasure (B), and post-session information-theoretic confidentiality against unbounded computational power (C) — built on a constant-memory O(1)-state streaming operator. Current main project, under review for the German Federal Research Allowance.
What is the .causal format?
A binary knowledge-graph format with deterministic inference embedded in the file itself — stored knowledge is amplified by a built-in inference engine, without a reasoning service and without hallucination. IEEE IRI 2026 full research paper, top 30% of all submissions.
What is GSSM?
A generalized state-space model family in which Mamba, S5, and LRU arise as special cases — the mathematical foundation of the lineage GSSM → O1 → o1-state, whose constant-memory state operator underpins O1-EITE.
Can compression-based analysis detect weak encryption?
Yes — as a black-box instrument on ciphertext alone: distributional signatures in NIST post-quantum ciphertext, trust verification of nano-IoT lightweight ciphers, and persistent cross-round carry leakage in ARX ciphers. Peer-reviewed at IEEE ICECET 2026 and IEEE-NANO 2026.
