STLS-AI is Sparkle’s patent-pending technology enabling secure, verifiable, and quantum-resilient communication between autonomous AI agents, edge workloads, APIs, and distributed network functions. Built on symmetric cryptography and powered by Arqit’s key agreement technology, STLS-AI removes certificates, public-key exchange, and asymmetric TLS handshakes—eliminating major fraud vectors and stopping impersonation at the transport layer. Validated across Sparkle’s global backbone in 2025, STLS-AI Core is available for operator trials and integration into production automation.
