Triple-nested digital signatures combining Ed25519, Dilithium-5 (ML-DSA-87), and FALCON-512. Defense-in-depth across three independent mathematical problems.
Every Triple Key signature nests three layers of cryptographic protection. Each layer signs the output of the previous, creating an unbreakable chain.
Each algorithm relies on a fundamentally different mathematical problem. A breakthrough against one leaves the other two fully intact.
Classical elliptic-curve signature, battle-tested across billions of TLS handshakes. Fastest verification of the three. Provides immediate backward-compatible security today.
NIST FIPS 204 standard. Module-LWE lattice construction at the highest security level (Category 5). Primary quantum-resistant layer with strong concrete hardness guarantees.
NTRU lattice-based hash-and-sign scheme, mathematically independent from Dilithium. Produces the most compact post-quantum signatures. Eliminates single-lattice-family risk.
Automated key rotation with zero-downtime overlap periods. Every rotation is cryptographically attested and optionally bound to a soul-bound NFT for on-chain audit.
Three layers of cryptographic signatures, all under 2ms combined. Production-grade latency for real-time applications.
Measured on AWS Graviton4 (ARM64, c8g.metal-48xl). All operations complete under 2ms.
Three endpoints. One API key. Full post-quantum signature stack in a single HTTP call.
