Core Capabilities

Deterministic Security Gateway

Eight foundational features that make AI governance verifiable, auditable, and compliant. Every feature is production-ready and powering DSG ONE today.

🔐

Deterministic Security Gateway

Every AI action is verified by SMT solver before execution

→Policy invariants verified by Z3 theorem prover
→8 core security theorems + 3 DeFi-specific proofs
→Static verification at design time, no runtime overhead
→UNSAT-certified constraints prevent policy violations

🔢

Gap-Free Sequence Generation

Monotonic, tamper-proof audit trail

→No skipped numbers = no hidden entries
→Atomic database operations prevent race conditions
→Per-organization sequence counters
→O(1) performance with BigInt support

#️⃣

Deterministic SHA-256 Hashing

Cryptographic proof of decision determinism

→Stable JSON serialization for reproducibility
→Request hash → Decision hash → Chain hash linkage
→Same input always produces same output (provably)
→FIPS 180-4 compliant SHA-256 implementation

⛓️

Hash Chain Verification

Detect tampering with cryptographic proofs

→Each entry links to previous via SHA-256 chain hash
→Modification of any entry breaks all downstream hashes
→O(n) full verification or O(1) point verification
→Enterprise audit trail immune to backdating

🌳

Merkle Tree Audit Proofs

Compact O(log n) compliance verification

→Binary tree of cryptographic hashes
→Prove any entry included without scanning all 1000s
→Pre-computed root hashes at checkpoint intervals
→SARIF format export for standards-based tools

🛡️

Replay Protection & Idempotency

Prevent duplicate processing and ensure determinism

→Nonce-based replay protection
→Idempotency keys for safe retries
→Request hash comparison for decision verification
→Cryptographic proof that input → output mapping is unchanged

✅

Enterprise Audit Compliance

Meet regulatory requirements with automated proof

→EU AI Act Art. 12/14 evidence pack included
→ISO 42001 AI governance readiness
→CCVS v1.2 compliance evidence chain (L1–L5)
→2173 tests covering all code paths (72.08% mutation score)

📋

SARIF Format Export

Standard compliance report for auditors

→Static Analysis Results Interchange Format (SARIF)
→Compatible with GitHub Code Scanning, SonarQube, etc.
→Automated compliance evidence generation
→Audit trail in industry-standard format
