| Abstract(in English) | Keeping anonymity for privacy protection or other purposes is a very important rights to live in the electronic society. In this regard, we should carefully examine cryptographic schemes in terms of the anonymity. There are two proposals for the signature scheme, threshold-multisignature scheme and threshold proxy signature scheme. The former scheme is a signature scheme combining the functionality of the threshold signature scheme and the multisignature scheme, and the latter scheme is a signature scheme combining the functionality of the threshold signature scheme and the proxy signature scheme. We analyze these signature schemes with respect to the anonymity and point out problems. Then we show an improved signature scheme solving these problems, and give its analyses in terms of the anonymity and other aspects. |
