# Security Model

### **Security Model**

zkShine’s security model enforces **three layers of protection:**

| Layer                   | Security Mechanism                 | Description                               |
| ----------------------- | ---------------------------------- | ----------------------------------------- |
| **Cryptographic Layer** | zk-SNARK/zk-STARK proof validation | Guarantees correctness without exposure   |
| **Network Layer**       | Encrypted relay & VPN tunneling    | Prevents IP or data interception          |
| **Execution Layer**     | On-chain proof verification        | Prevents tampering or invalid submissions |

Additional safety measures:

* AES-256 encryption for all storage and message data
* SHA-3 hashing for proof commitments
* Multi-node redundancy to prevent data correlation attacks
