Recently,somedivisibleelectroniccash(e-cash)systemshave been proposed. However, in existing divisible e-cash systems, efficiency or unlinkability is not sufficiently accomplished. In the existing efficient divisible cash systems, all protocols are conducted in the order of the polynomial of log N where N is the divisibility precision (i.e., (the total coin amount)/ (minimum divisible unit amount)), but payments divided from […]
