  Abstract

The increase of electronic commerce leads to the increasing attention to the way customers pay and a large number of researches on payment system. Recently many researches on a system which provides anonymity in order to protect user's privacy have been carried out. And some potential problems from that system are being reviewed by anonymity control system. This thesis will include the following. First, I want to analyze the old scheme related to divisible and examine general ideas of anonymity control. Second, I propose a new blind signature in addition to KCDSA, the standard digital signature in Korea. The last one I want to propose is a new electronic cash system with the divisible for more efficient use of electronic cash which can control anonymity with the help of trustee.
