(WonderfulEngineering) The Japanese government has requested to invest money in quantum cryptography so that it can be made functional by 2027. If this is achieved, the system used in satellites and lasers will become so secure that it cannot be hacked by any means. The Japanese government is planning to invest in a space-based security system so that its secrets can be kept safe. The system will be considered virtually unhackable if it uses quantum cryptography communications in it.
Japan has its security on high alert since North Korea started making threats of nuclear action its neighbor and the US. Local media of Japan is saying that he plans to test the quantum cryptography system is in the year 2022 and the system will be fully functional by 2027.
The proposed system will work when an orbiting satellite receives instructions to deliver a set of keys to both sender and receiver. The sender uses this key to encrypt its data and the receiver uses its key to decode the data. The keys are sent through a powerful laser beam of light particles.
