| Abstract(in English) | Although previously propossed key revocation schemes based on secret sharing have an advantage that the size of terminal keys and that of data to derive the message keys are not dependent on the total terminal number, there is a problem that the key revocation number cannot be flexibly changed after setting up the schemes. In this paper, we consider secret sharing schemes with threshold changeability to provide the key revocation schemes with changeability of revocation number. Furthermore, we show that our proposed schemes are efficient compared to the schemes previously proposed. |
