<h1>Indian companies partner to develop first indigenous quantum-secure satellite with post-quantum cryptography technology</h1> Two Indian companies have signed a memorandum of understanding to develop the country's first indigenous quantum-secure satellite and space-based technologies. The partnership combines one company's expertise in spacecraft systems engineering with another's specialization in post-quantum cryptography. Their collaboration will focus on quantum-secure satellite payloads, encrypted satellite-ground communications, AI-driven mission planning, and quantum-resilient satellite systems. The alliance aims to protect India's space infrastructure from future quantum computing threats while supporting domestic manufacturing and technological self-reliance in the space sector.
