Full Form of QSX
What is QSX?
Quantum Secure Exchange (QSX) is an advanced cryptographic protocol designed to facilitate ultra-secure data transmission by leveraging principles of quantum key distribution (QKD) and post-quantum cryptography. In India, QSX is gaining traction among financial institutions, government agencies, and tech startups that require protection against both classical and quantum-based cyber threats. The protocol ensures that any attempt to intercept the communication alters the quantum state, immediately alerting both sender and receiver. QSX is primarily used in sectors handling sensitive data, such as banking, defence, and critical infrastructure. It is deployed in pilot projects by Indian cybersecurity firms and research labs under initiatives like the National Quantum Mission. Although still emerging, QSX is considered the next-generation of secure communication, replacing older standards like SSL/TLS. For students preparing for competitive exams like GATE or UPSC, understanding QSX is relevant to questions on cyber security, quantum computing applications, and India's digital infrastructure. The protocol name is often seen in technical white papers and policy documents related to India's cyber resilience strategy.
