Italian operator unveils patent-pending technology for secure, verifiable AI-to-AI interaction, extending its quantum-safe portfolio that already includes a cloud-native service on AWS
Sparkle has introduced STLS-AI (Symmetric Transport Layer Security for Agentic Artificial Intelligence), a patent-pending technology designed to enable secure, quantum-resilient communication between autonomous AI agents.
Announced at Mplify’s Global NaaS Event in Dallas, STLS-AI aims to create a new trust framework for emerging agentic AI systems – digital entities capable of planning, negotiating, and interacting without human oversight. As such systems proliferate, Sparkle said, the need for authentication and verifiable communication among AI agents is becoming critical.
The new service allows agents to identify and verify each other without the use of certificates or centralised authorities, promising faster and more secure data exchanges. During live demonstrations linking Dallas, London and Northern Virginia, Sparkle showcased STLS-AI’s ability to deliver verifiable transatlantic AI communications, which the company described as “the beginning of a new era of secure AI-to-AI interaction”.
Beyond the technology demonstration, Sparkle sees STLS-AI as an enabler for enterprises, developers and system integrators building agent-based applications or working on quantum technologies. The platform is designed to guarantee both data protection and agent identity verification, paving the way for secure interaction across digital ecosystems, according to the operator.
“With STLS-AI, we are laying the foundation for a trusted AI ecosystem, where autonomous entities can interact with the same integrity and accountability that define human digital identities,” said Sparkle chief marketing & product management and board director member and co-CEO at Mplify Daniele Mancuso (above). “By extending quantum-safe trust from the network to the intelligence itself, service providers will become the trust brokers of the AI-driven economy, ensuring that the next generation of intelligent systems can prove who they are, connect, collaborate, and act securely.”
The service, which is patent pending, will be commercially available by the end of 2026, with proof-of-concept opportunities open immediately.
The announcement builds on Sparkle’s broader push into quantum-secure networking. In June, the company launched its Quantum Safe over Internet (QSI) service to Amazon Web Services customers via the AWS Marketplace. That cloud-native VPN solution secures connectivity between enterprise sites and cloud regions, protecting data against future quantum threats.
Together, QSI and STLS-AI give Sparkle quantum-safe communications services spanning both network and intelligence layers.
