Scalable Divisible E-cash
[chapter]
2015
Lecture Notes in Computer Science
Divisible E-cash has been introduced twenty years ago but no construction is both fully secure in the standard model and efficiently scalable. In this paper, we fill this gap by providing an anonymous divisible E-cash construction with constant-time withdrawal and spending protocols. Moreover, the deposit protocol is constant-time for the merchant, whatever the spent value is. It just has to compute and store 2 l serial numbers when a value 2 l is deposited, compared to 2 n serial numbers
