Researchers from Don State Technical University have proposed an encryption method that uses the phenomenon of quantum teleportation. It will make it harder for hackers to get hold of the data. The scientists shared their findings in the journal Electronics.
Experts have created a module to the common BB84 encryption protocol that makes the process of hacking a system, if not completely useless, at least extremely difficult and unprofitable. It is based on the principle of quantum teleportation, in which it is impossible to create an exact copy of a quantum system without destroying its source. To avoid eavesdropping on the communication channel, it is suggested to complete the semantic part of the message with a series of characters that are meaningless to the hacker.
The implementation of the modification, which the scientists stated in the article, will increase the working distance of the protocol from 70 kilometers to 511 kilometers.
