| 抄録 | IT social infrastructures based on the e-Japan Strategy and the development of e-commerce are rapidly increasing. According to this trend, documents are changing from paper-based to digital data. If only digital-signature techniques are used for digital data, it is difficult to guard against fraudulent practices. It has been found that time stamping techniques, which, when combined with digital signatures, provides an effective solution to this problem. In this paper, presented are the results of basic time-transfer measurements and future plans, which are needed by the National Time Authority. |
