The Indian Space Research Organisation (ISRO) is developing satellite-based quantum communication technology to enhance data security. This technology uses quantum cryptography, an encryption method resistant to hacking. The ISRO recently demonstrated this technology at the Indian Mobile Congress, highlighting its potential to secure regular communication with complex codes. The agency is also implementing quantum key distribution, a technique that generates secure, random codes. Last month, ISRO successfully demonstrated free-space quantum communication over 300 meters, including live video-conferencing using quantum-key-encrypted signals. This represents a significant step towards secure satellite data communication using quantum technologies.
Quantum Communication: The Future of Secure Data Transmission
The Indian Space Research Organisation (ISRO) is developing a new project focused on satellite-based quantum communication technology. This initiative comes at a time when data breaches are a significant concern due to the prevalence of spyware like Pegasus, which can infect almost any device or software.
Quantum communication uses a form of encryption known as quantum cryptography, which is resistant to hacking. This encryption method enhances end-to-end security, alerting users if their information is being compromised. The Indian space agency recently showcased this satellite-based quantum communication technique at the Indian Mobile Congress (IMC) 2023.
Quantum Key Distribution: A New Security Technique
The ISRO is employing a new technique called quantum key distribution to address the potential security challenges posed by the advent of powerful quantum computers. This method generates highly secure and random secret codes, which can make regular communication exceptionally secure and resistant to hacking.
The Indian space agency successfully demonstrated free-space Quantum Communication over a distance of 300 meters last month. This demonstration included live video-conferencing using quantum-key-encrypted signals, marking a significant achievement for unconditionally secure satellite data communication using quantum technologies.
Quantum Communication vs Conventional Encryption Systems
Quantum Key Distribution (QKD) technology, which underpins Quantum Communication technology, ensures unconditional data security based on the principles of quantum mechanics. This level of security is not achievable with conventional encryption systems.
Conventional cryptosystems used for data encryption rely on the complexity of mathematical algorithms. In contrast, the security offered by quantum communication is based on the laws of Physics. As a result, quantum cryptography is considered ‘future-proof’, as no future advancements in computational power can break a quantum cryptosystem. This makes quantum communication a promising solution for secure data transmission in the future.
