RCRE: Reversible Collapse-Resistant Encryption

RCRE is a novel experimental cryptographic primitive inspired by the Reversibility Kernel (RK) theory of quantum collapse.
Instead of relying purely on computational hardness, RCRE encodes messages into thermodynamically modeled coherence structures —
where incorrect decryption attempts cause entropy buildup, ultimately triggering irreversible collapse.

"Persistence attracts entropy — and collapse is not failure, but the final whisper of structure lost."

🔥 Features

• Mutual information decay modeled with a Persistence Equation
• Structural collapse if entropy exceeds a threshold
• XOR-based reversible encoding for testbed simplicity
• Simulated entropy injection with every "probe"
• Prints real-time S(η) values with each attempt
• Reversible unless you push the entropy too far — then it's gone forever

🛠️ Build Instructions

⚙️ Prerequisites

• Rust (latest stable): https://rust-lang.org/tools/install

🧱 Compile

bash cargo build --release

🚀 Run cargo run

use rcre_crypto.exe --encrypt <input.txt> <output.enc> --key <secret> rcre_crypto.exe --decrypt <input.enc> <output.txt> --key <secret>

e.g.:

Encrypt

rcre_crypto.exe --encrypt D:/test/data/test.txt D:/test/data/test.enc --key ultra_secret

Decrypt

rcre_crypto.exe --decrypt D:/test/data/test.enc D:/test/data/test.dec --key ultra_secret

🧪 Example Output

Encrypted message: [38, 1, 24, 30, ...]
Attempt 1 — Persistence S(η) = 1.0000, Collapsed = false
Decrypted: Collapse-resistant crypto is cool!
...
Attempt 10 — Persistence S(η) = 0.3043, Collapsed = false
Decrypted: Collapse-resistant crypto is cool!```

Once the persistence drops below ENTROPY_THRESHOLD, the RK structure collapses, and further decryption will fail irreversibly.

🧮 Core Equations
The model uses the Persistence Equation:

S(η) = exp[ -α ⋅ (1 - η) ⋅ Q / T ]

Where:
η = mutual information (1.0 → 0.0)
Q = cumulative entropy injected by adversary/decryption attempts
T = thermodynamic buffering capacity (resilience)
α = structural fragility constant

Collapse is triggered when:
S(η) < ENTROPY_THRESHOLD
