| Outline of Final Research Achievements |
For the realization of the Vernam cipher in the wireless communication, I proposed a method to acquire a large quantity of secret key effectively in secret key agreement using radio. The proposed method uses the irregular setting of the intermittent section based on the change of radio propagation characteristics and choice of the random number series in the section. The result of the computer simulation shows agreement of the setting section and complete secret key agreement being possible and that a proposed method is useful. In addition, as the alternative method that the acquisition of a large quantity of secret key was possible, I examined new secret key agreement and secure communication using radio. The result of the superiority and inferiority comparison with the alternative method shows the superiority of the proposed method.
