DRDO, PSU and Private Defence Sector News

[NAMICA]

A private company whose product I posted sometime back had already demonstrated it , if I remember correctly.

Can u confirm which type of quantum computer is under development.

 

[Chinmoy]

Now what is PKI?

Public key Interface.

In WAN communication over open network when you have to do a secure communication, there are two way of doing it. Using a VPN tunnel or use a encryption algorithm. PKI is used in a data encryption where a 64, 128, or 256 bit SSL encryption is used where the key is shared in between sender and receiver. So anyone who receives the key would be able to decrypt the message. This could be achieved by intercepting message and use simple algorithm. Although breaking a 256 bit encryption key would require a Super Computer. In some corporate and govt sector, these keys are shared via dedicated receiver unit. Even the OTP is kind of PKI.

In case of Quantum key distribution, these keys gets generated by involving quantum mechanics principle. Now if to break a 256 bit SSL encryption you would require a Super Computer, to break a Quantum key encryption, you would require a bunch of those SCs.

You don't need Quantum Computers to develop a QKD system.

In a giant leap towards secure communication DRDO established and validated the performance and security of Quantum Key Distribution over 12km intra-city link between two laboratories.
Secure communications are vital for defence and strategic agencies world over and distribution of encryption keys from time to time is an important requirement in this context. Sharing of keys over the air or wired links requires encryption, which in turn requires encryption keys to be pre-shared. Quantum based communication offers a robust solution to sharing the keys securely. Defence Research & Development Organisation (DRDO) undertook the project for development of this technology.
A milestone of this project was achieved today when DRDO developed Quantum Key Distribution (QKD) technology underwent trials in Hyderabad between two DRDO labs, DRDL and RCI, to show secure communication. Raksha Mantri Shri Rajnath Singh congratulated the DRDO team for successful demonstration of QKD communication.
The technology is developed by CAIR, Bengaluru and DYSL-QT, Mumbai. Quantum Communication using time-bin Quantum Key Distribution (QKD) scheme was performed under realistic conditions. The setup also demonstrated the validation of detection of a third party trying to gain knowledge of the communication. Quantum based security against eavesdropping was validated for the deployed system at over 12kms range and 10dB attenuation over fibre optic channel.
Continuous wave laser source was used to generate photons without depolarization effect. The timing accuracy employed in the setup was of the order of picoseconds. The Single photon avalanche detector (SPAD) recorded arrival of photons and key rate was achieved in the range of kbps with low Quantum bit error rate. Software was developed for data acquisition, time synchronization, post-processing, determining Quantum bit error rate and extracting other important parameters.
The work being done at DRDO will be used to enable start-ups and SMEs in the domain of Quantum information technologies. It will also serve to define standards and crypto policies that can leverage QKD system in a unified Cipher Policy Committee (CPC) framework for more secure and pragmatic key management for current and future military cryptographic systems.

Found this in my HDD, DRDO Developed Laser Cross Section Measurement and Imaging (LACSMI) system under Engineering Application of Stealth Technology.

Laser Cross section is similar Like Radar cross Section .

Isn't quantum key encryption unbreakable ?

 

[Chinmoy]

Isn't quantum key encryption unbreakable ?

Not really. You would need a Quantum computer to break it.

Super cray would need nearly 100 years to break a 256 bit SSL encryption. But the IBM Summit could do this in 2 years time.

 

[ezsasa]

Not really. You would need a Quantum computer to break it.

You have any academic paper supporting this theory?
Not from a theoretical physicist or a futurist , but rather from someone who has worked on it.

 

[Tuco]

They could have just got into an arrangement with QNU instead of reinventing the wheel saving some money in the process. If a particular technology is already present in the country customize it, this also will help tech startups. If this was done by private competing company I can understand.

Is it a quantum computer?

Some info regarding optionally manned kiran aircraft-

1. It will have two modes of operation OPA and UAV.

2. In OPA mode pilot will manually control the aircraft sitting in cockpit.

3. UAV mode will be further divided into 3 modes - external pilot (by runway), internal pilot (by console) and complete autonomous mode.

4. There will be an Integrated Control Computer (ICC). There will be three actuators for the existing controls. The commands from the ICC will direct the actuator movements. The commands from the ICC could be from the autopilot (new) or from the internal/external pilot.

5.The pilot has a master switch to decide the mode of the aircraft: OPA/UAV. In OPA mode internal pilot is flying it manually. ICC keeps giving commands, but the actuators are declutched. In UAV mode, it can be externally or internally piloted or autonomous using the autopilot.

6. HAL rotary UAV division is also working on some stellar projects.

 

[NAMICA]

In short we will be demonstrating technology which will be present in 6th gen aircraft and most probably will be used in AMCA mk2.

Tell me about Stellar project if its not confidential.

It's easy to guess that what projects rotary division will be undertaking.
