14. Q-PARAKRAM: A defence-grade quantum-safe encryptor providing up to 1 Gbps throughput for Layer 2/3 networks. It incorporates NIST PQC algorithms and other proprietary algorithms and is designed to provide robust quantum-resistant security for strategic and defence communications.
“The Quantum Product Series combines QKD technologies and PQC-based solutions to enable secure quantum key generation and distribution and are designed to protect communications against threats posed by future quantum computers. The quantum portfolio from C-DOT also spans specialised quantum communication components that can go in building quantum-safe security solutions for existing and next-generation networks by the eco system working in this area,” the Ministry said.
“The products reflect the Centre’s focus on translating indigenous research and innovation into deployable solutions for securing India’s communication infrastructure in the emerging quantum era. These products have been developed to address emerging cybersecurity challenges associated with the advent of quantum computing and to strengthen the security and resilience of India’s communication networks.”
A Quantum Product Series booklet, bringing together C-DOT’s indigenous quantum solutions, was also launched during the event. The publication details the organisation’s work in QKD and PQC and its efforts to develop secure, resilient and future-ready communication technologies.
