| Abstract(in English) | This paper discusses how to achieve secure data transmission between two computers without wiretapping. Usually, secret data is encrypted before transmission and decripted after receipt. However, the more advanced computers are used, the more easily the encrypted data is unreasonably decripted. It is useful to transmit secret data through multiple transmission routes since even though a part of the data is intercepted, it is difficult to get whole the data. On the other hand, data transmission without a computer network, i.e. by using storage devices, is an altanative method. Hence, this paper proposes a secret data transmission method by using multiple USB flush memory devices. Here, a secret data is divided into multiple parts and each of them is encrypted by a different encryption key. The encryption key is stored into a USB flush memory device which is different from one in which a part of data encrypted by the key is stored. By using this method, even if one of the USB flush memory devices is stolen, it is difficlut or impossible to decript a part of secret data stored in it. The authors evaluate a prototype system and achieve encryption and decription overhead less than 20% degradation of access bandwidth. |
