# Security Policy

## 🔒 Security Overview

HYPERION implements cryptographic protocols for zero-knowledge proof generation. This document outlines our security practices, known limitations, and responsible disclosure process.

## Supported Versions

| Version | Supported          | Security Updates |
| ------- | ------------------ | ---------------- |
| 0.1.x   | :white_check_mark: | Active           |

## 🔐 Cryptographic Security

### Security Model
- **Soundness**: 2^(-λ) security bound with λ=128+ configurable parameter
- **Zero-Knowledge**: Computational ZK via Fiat-Shamir transform
- **Completeness**: Perfect completeness for valid executions

### Cryptographic Primitives
- **FRI Protocol**: Sub-linear proof verification
- **Goldilocks Field**: 64-bit security level
- **Reed-Solomon Codes**: Error correction for proximity testing
- **Merkle Trees**: Efficient commitment schemes

### Known Limitations
- **LLVM Frontend**: Basic function support only (advanced features TBD)
- **Memory Bounds**: Configurable but not automatically verified
- **Side Channels**: Not formally analyzed for timing attacks

## 🚨 Reporting Security Vulnerabilities

### Responsible Disclosure Process

1. **Do not** create public GitHub issues for security vulnerabilities
2. **Email** security@hyperion-zkvm.dev with details
3. **Allow** 90 days for fix before public disclosure
4. **Include**:
   - Description of the vulnerability
   - Steps to reproduce
   - Potential impact assessment
   - Suggested mitigation

### Response Timeline
- **Initial Response**: Within 48 hours
- **Vulnerability Assessment**: Within 7 days
- **Fix Development**: Within 30 days for critical issues
- **Public Disclosure**: Coordinated with reporter

## 🛡️ Security Best Practices

### For Users
- Use latest stable version
- Validate proof parameters for your security requirements
- Run in isolated environments for sensitive computations
- Verify proof outputs independently when possible

### For Contributors
- All cryptographic changes require security review
- Maintain formal security proofs
- Update this document for security-relevant changes
- Consider side-channel vulnerabilities

### Development Security
- **No unsafe code** in cryptographic primitives
- **Comprehensive testing** including fuzzing
- **Static analysis** with Clippy
- **Dependency auditing** with `cargo audit`

## 🔍 Security Audit Status

### Completed Audits
- **Internal Cryptographic Review**: ✅ All tests passing
- **Formal Verification**: ✅ Core algorithms verified

### Planned Audits
- External cryptographic audit (Q1 2025)
- Side-channel analysis (Q2 2025)
- Formal verification tools integration (Q2 2025)
