The Data Will Be More Secure, ISRO's Precedent in New Quantum Technology

This is a significant experiment in the exchange of quantum-key encrypted data between artificial satellites and ground stations. Quantum encrypted message transactions will be possible through this very secretly. The Indian Space Research Organisation (ISRO) set a precedent by sharing a free Quantum Key at a distance of 300 meters on Monday. Quantum-key encrypted signals are transmitted between the two buildings of the Ahmedabad Space Application Center. The Indian Space Research Organization conducted a live video conference of the entire process.

This is a significant experiment in the exchange of quantum-key encrypted data between artificial satellites and ground stations. Quantum encrypted message transactions will be possible through this very secretly. "This is a major milestone in communicating through secure satellite data using quantum technology," ISRO said in a press release on Monday.

Any data transmission can be highly secured through quantum cryptography. No other third party can break this encryption. In cases where the exchange of information needs to be highly secure, it will point the way to a new future. This technology will further ensure the security of information in the case of banks, the army, etc. Only quantum computers have the ability to break this type of complex encryption. So far, the concept of a quantum computer is only in the pen. In fact, no country has yet been able to make it. However, almost every powerful country is trying to create a quantum computer.

Data is stored as bits on ordinary computers. That is, through 0 or 1, the work is done according to binary logic. But quantum computers use qubits. The value of protons or electrons is taken as 0 or 1. Also, any possible combination of 0 and 1 can be. For now, ISRO is considering applying this technology to more remote areas. The next step is to exchange information in this manner from any two space research centers in the country.

In this case, ISRO has invented several Made in India technologies. ISRO has developed a receiver called NavIC (Navigation with Indian Constellation). This maintains the synchronization of time between the transmitter and the receiver module. This is actually the Indian version of the satellite-based positioning system.
