🔐Prototype of cryptographic communication device realizing high security by using random noise
Long-distance cryptographic communication possible at the theoretically impossible level
Hitachi has developed a cryptographic communication technology that realizes a high degree of security that is virtually impossible to decrypt in virtually an environment connected to the Internet via a LAN cable and prototyped a communication device equipped with this technology.
By installing a noise generator in the transmitter and transmitting randomly generated noise in addition to the data necessary for encrypted communication, it becomes difficult to decrypt the encrypted data other than the canonical recipient who knows how to remove the noise.
Specific transmission paths such as optical fibers required for quantum cryptographic communication become unnecessary and communication to various parts of the world connected by the LAN cable is possible.
