| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Users of cloud computing could not wipe away the anxiety about the data and programs may be abused or leaked, because users submit their almost whole data and programs to a cloud provider. Those data and programs usually embody the company’s stored knowledge. Then they shall be key elements of core competences of the user’s company. We study countermeasures against the abuse or leakage of data and programs caused by cloud providers’ careless or intentional crime. As one of those countermeasures, “secret sharing and secret computation by secure multi parties method” is studied and used practically in some applications. This method can calculate addition or subtraction easily, but to do multiplication it needs rather complex processes. We propose an idea to do multiplication and division easily as well as addition and subtraction. | |
