【 摘 要 】

This paper presents an electronic cash schemeusing the continued fractions theory. Continued fractions have already some utilities in cryptography such as in the cryptanalysis of RSA [17] or in the design of some stream ciphers [11]. In order to achieve our prepaid ecashscheme, we will use the continued fraction expansion of some irrationals numbers, although the same scheme can be obtain with a block cipher algorithm like AES or with some pseudo-random generators. Our e-cash scheme has two aims: the first one is to create a payment system independent of current constraints such as the revocation ofanonymity (in the double spending case) or the obligation for those who want to use the e-cash, to have a bank account.The second aim is to propose in this paper a solution which prevent the copy of our e-coins and allow if necessary the reimbursement of the user with e-cash.
