Mitsubishi Electric developed the technology to apply quantum cryptography that theoretically cannot be tapped to mobile phone. This is the world’s first technology to apply quantum cryptography to mobile phone. The technology connects communication partners by optical fiber and sets special equipment in the offices. When a mobile phone is connected to the special equipment temporarily, the mobile phone can download the encryption key. Once the encryption key is downloaded, the user can carry the mobile phone like a standard mobile phone. In the communication mode, he can send his voice data by encrypting them using the encryption key. Used encryption keys will be erased. Quantum cryptography is called the ultimate code language because it can detect the tapping by the third party. The company plans to put the technology into practical use in three to five years. The technology will be displayed in Quantum Cryptography and Communications 2010 scheduled for 18th-20th October in Tokyo.
