+# ASVS 9.1.2 Security Audit Report
+
+## Executive Summary
+
+- **Repository:** apache/mahout
+- **Audit Date:** May 02, 2026
+- **Auditor:** Tooling Agents
+- **ASVS Requirement:** 9.1.2 — Verify that only algorithms on an allowlist can be used to create and verify self-contained tokens, for a given context. The allowlist must include the permitted algorithms, ideally only either symmetric or asymmetric algorithms, and must not include the 'None' algorithm. If both symmetric and asymmetric must be supported, additional controls will be needed to prevent key confusion.
+- **Level:** 1
+- **Section:** Token source and integrity
+- **Files analyzed:** 2 relevant out of 393 total, 35 skipped
+
+### Finding Summary
+
+| Severity | Count | Status |
+|----------|-------|--------|
+| Critical | 0 | ✓ |
+| High | 0 | ✓ |
+| Medium | 0 | ✓ |
+| Low | 0 | ✓ |
+| **Total** | **0** | **N/A - No Applicable Code** |
+
+**Overall Assessment:** NOT APPLICABLE — The provided files are pure Markdown documentation with no executable code, no token handling, no JWT/SAML processing, and no cryptographic algorithm selection logic.
+
+---
+
+## Security Controls Inventory
+
+| Control | Status | Location | Purpose | Coverage |
+|---------|--------|----------|---------|----------|
+| JWT/Token creation | **Not Present** | N/A | Create self-contained tokens | Not applicable |
+| JWT/Token verification | **Not Present** | N/A | Verify token integrity and authenticity | Not applicable |
+| Algorithm allowlist | **Not Present** | N/A | Restrict permitted cryptographic algorithms | Not applicable |
+| 'None' algorithm rejection | **Not Present** | N/A | Prevent algorithm bypass attacks | Not applicable |
+| Key confusion prevention | **Not Present** | N/A | Separate symmetric/asymmetric key handling | Not applicable |
+
+---
+
+## Critical File Review
+
+### Documentation Files
+
+| File | Type | Lines | Token-Related Functions | Security-Sensitive Operations | ASVS 9.1.2 Relevance |
+|------|------|-------|-------------------------|-------------------------------|---------------------|
+| `docs/advanced/pqc.md` | Markdown | N/A | None | None | Not applicable — theoretical quantum circuit guide |
+| `docs/advanced/gap-analysis.md` | Markdown | N/A | None | None | Not applicable — architecture gap analysis |
+
+**Summary:** No executable code present in either file. Both files contain only documentation content with no token handling, cryptographic operations, or authentication mechanisms.
+
+---
+
+## Findings
+
+### No Vulnerabilities Identified
+
+The audit scope consisted entirely of documentation files (Markdown format) containing:
+
+- Theoretical explanations of Parameterized Quantum Circuits
+- Mathematical formulas for quantum gate operations
+- Gap analysis for implementing PQC features in the QuMat library
+- Illustrative Python function signatures (non-executable examples)
+
+**The following token-related elements are absent:**
+- Self-contained token (JWT, SAML) creation or verification logic
+- Cryptographic algorithm selection or configuration code
+- Authentication or authorization mechanisms
+- Executable code of any kind
+
+**Applicability Assessment:**
+
+| Criterion | Present | Assessment |
+|-----------|---------|------------|
+| Self-contained token handling | ✗ | No token creation or verification |
+| JWT creation/verification | ✗ | No JWT libraries or implementations |
+| SAML assertion processing | ✗ | No SAML handling |
+| Cryptographic algorithm selection | ✗ | No algorithm configuration |
+| Executable code | ✗ | Documentation only |
+
+**Conclusion:** ASVS 9.1.2 requirements cannot be evaluated against the provided files as they contain no relevant executable code or token handling logic.
+
+---
+
+## Positive Security Patterns
+
+1. **No Hardcoded Credentials**
+   - Documentation files contain no secrets, API keys, tokens, or sensitive credentials
+   - No examples demonstrating insecure credential storage
+
+2. **No Insecure Algorithm Recommendations**
+   - Gap analysis documentation does not prescribe weak cryptographic practices
+   - No guidance that would lead to insecure implementations
+
+3. **Separation of Concerns**
+   - Documentation appropriately focuses on quantum computing concepts
+   - Does not conflate security mechanisms with functional documentation
+
+---
+
+## Architecture Observations
+
+1. **Cloud Backend Integration (Future Consideration)**
+   - The QuMat codebase (referenced in `gap-analysis.md`) integrates with cloud quantum backends (Qiskit, Cirq, Amazon Braket)
+   - These integrations would require secure credential handling and potentially token-based authentication
+   - No implementation code provided for security assessment
+
+2. **Hardware Execution Support (Planned Feature)**
+   - Gap analysis identifies future needs for "job submission, monitoring, and result retrieval"
+   - These features would likely involve token-based authentication with cloud providers
+   - Implementation not yet present per the analysis documentation
+
+3. **Library Context**
+   - Per architectural context: This appears to be a single-user scientific computing library
+   - Absence of authentication/authorization systems may be intentional for this use case
+   - Multi-tenant service patterns (requiring token validation) are not in scope
+
+4. **Security Responsibility Boundary**
+   - If cloud backend authentication is implemented, token handling would occur at integration points
+   - Security controls would be needed at the boundary between QuMat and external quantum services
+
+---
+
+## Recommendations Summary
+
+### Immediate Actions
+*None required* — No executable code in audit scope
+
+### Short-term Recommendations
+
+**If token-based authentication is implemented for cloud quantum backend communication:**
+
+1. **Establish Algorithm Allowlist**
+   - Define explicit allowlist of permitted algorithms (e.g., `RS256`, `ES256`, `PS256`)
+   - Document rationale for algorithm selection based on security requirements
+   - Implement allowlist validation before any token verification
+
+2. **Reject 'None' Algorithm**
+   - Explicitly reject tokens using the `none` algorithm
+   - Validate algorithm header field is present and non-empty
+   - Implement defense-in-depth by checking at multiple layers
+
+3. **Prevent Key Confusion**
+   - Store symmetric and asymmetric keys in separate key stores
+   - Implement type checking to ensure correct key type for algorithm
+   - Use distinct key identifiers for different algorithm families
+
+### Long-term Recommendations
+
+1. **Comprehensive Security Audit**
+   - When authentication code is implemented, conduct full ASVS Level 1 audit
+   - Include all token handling, key management, and cryptographic operations
+   - Review integration points with external quantum cloud services
+
+2. **Security Testing**
+   - Implement automated tests for algorithm allowlist enforcement
+   - Test rejection of `none` algorithm and other attack vectors
+   - Validate key confusion prevention mechanisms
+
+3. **Documentation**
+   - Document token handling security architecture
+   - Provide secure implementation guidance for developers
+   - Include threat model for token-based authentication flows

+
+## Audit Limitations
+
+**To properly audit ASVS 9.1.2 compliance, the following file types would be required:**
+
+- Authentication middleware or modules
+- JWT creation and verification utilities
+- OAuth 2.0 / OpenID Connect integration code
+- API token validation logic
+- Cryptographic library configuration
+- Key management implementations
+- Session management code
+
+**Recommendation:** Provide executable source code containing token handling logic for meaningful ASVS 9.1.2 assessment.
