India to Develop First Indigenous Quantum-Secure Satellite in Partnership Between Space TS and Synergy Quantum.

Science and Technology | Dated: 09 Jul 2025

India has taken a major leap in space cybersecurity with Bengaluru-based Space TS signing an MoU with Switzerland’s Synergy Quantum in July 2025. The partnership aims to develop the nation’s first indigenous quantum-secure satellite to ensure safe, encrypted communication by leveraging post-quantum cryptography and AI-integrated satellite technologies.

🎯 Key Highlights:

  • - The satellite will be embedded with post-quantum cryptography (PQC), protecting data transmission from threats posed by future quantum computers. Unlike classical encryption methods like RSA and ECC, PQC ensures long-term confidentiality through quantum-resistant protocols, hardened firmware, and secure crypto-chips—making the satellite resilient against quantum-era cyber threats.
  • - Space TS will handle the core satellite engineering, including payload integration and orbital mission planning, while Synergy Quantum will contribute post-quantum software architecture and encryption layers. The collaboration’s aim is to build end-to-end quantum-safe communications, connecting ground stations, satellite constellations, and drones using AI-assisted control mechanisms and secure key exchanges.
  • - This indigenous satellite initiative is part of the Indian government's Atmanirbhar Bharat vision, aiming for technological self-reliance in cybersecurity and space infrastructure. It supports national security, defence systems, critical infrastructure resilience, and digital sovereignty, putting India alongside leading nations like the EU and China in quantum space initiatives.

💡 Other Important Facts:

  • (i) The satellite will also act as a platform for Quantum Key Distribution (QKD), a highly secure form of encryption key sharing. Its additional functionalities will include encrypted telemetry systems, autonomous control over AI-powered constellations, and secure storage and communication frameworks suited for national and commercial defence applications.
  • (ii) Once operational, the satellite will also be used for advanced technologies like secure swarm drone operations, multi-orbit encrypted networks, and space-based cloud computing. This could give India a significant edge in both civilian and defence quantum applications, strengthening its presence in the fast-growing quantum communication ecosystem globally.
