....key management can be made independent of any central authority, we refer the reader to [8] We will now discuss the way we envision the use of payments in a multi hop cellular network. Our approach. Instead of using one payment token per payee (as is done in traditional micro payment schemes [1, 6, 9, 10, 13, 16, 18, 21, 22]) we use one per packet, letting all relaying nodes verify whether this token corresponds to a winning ticket for them. To avoid forged deposits, the packet originator needs a secret key to produce the token (not unlike other payment schemes. To discourage colluders from collecting payments for ....

....In 1981, Lamport applied the idea to the problem of dynamic passwords [11] and most recently Pedersen applied the Winternitz idea to micro payments [7] as mentioned above the scheme is part of the CAFE payment system. Independent from our work two other groups came up with very similar schemes [12, 13]. Our proposal is very similar to Pedersen, but it provides the following improvements: ffl The coupon chains are securely bootstrapped with iKP without the need for secure hardware as in CAFE. ffl Means are provided to protect the integrity of the product description for which the coupon is ....

....Micropayments. Payment schemes that emphasize the ability to make payments of small amounts are called micropayment schemes. Several micropayment schemes have been suggested, including Millicent[10] by Manasse et al. the Payword and MicroMint[16] schemes of Rivest and Shamir, Anderson s NetCard [2] scheme, Jutla and Yung s PayTree[7] Hauser et al. s Micro iKP [5] the Micropayment Transfer Protocol (MPTP) of the W3C [4, 18] the probabilistic polling scheme[6] of Jarecki and Odlyzko, the Electronic Lottery Ticket proposal[15] of Rivest, Wheeler s similar Transactions Usings Bets [19] ....

....Payments [29] previously known as Minipay ) While the former gains its speed by putting complete trust in the payment system provider, the latter achieves its eciency relying on the assumption that in the case of small payments a posteriori fraud detection is sucient. A number of proposals [26, 28, 36, 37] were especially designed for situations where a sequence of small payments need to be made to the same merchant. Such situations occur in pay per web page services, or in streaming data services such as video on demand. These systems amortize the cost of an initial setup operation over extremely ....

....proposed for the mobile system UMTS (cf. Sect. 1) and the payment scenario for basic and value added services in UMTS. The cryptographic mechanism employed in the tick payment protocol is based on Lamport s password scheme [Lamp] Later Pedersen, Rivest and Shamir [RiSh] and Anderson et al. [AnMS] independently proposed the same mechanism for the payment of small amounts. Hauser et al. HaSW] who were aware of Pedersen s work, proposed to integrate the mechanism with IBM s iKP (Internet Keyed Payment Systems) protocol for credit card based electronic transactions. An extension of the ....

....values) Similar chains have been previously proposed for different purposes: by Lamport [9] and Haller (in S Key) for access control [7] and by Winternitz [11] as a one time signature scheme. The application of this idea for micropayments has also been independently discovered by Anderson et al. [2] and by Pederson [14] as we learned after distributing the initial draft of this paper. We discuss these related proposals further in Section 5. The user authenticates a complete chain to the vendor with a single public key signature, and then successively reveals each payword in the chain to the ....

....Wayner (private communication) has suggested a variation on MicroMint in which coins of different values are distinguished by publicly known predicates on the x values. 5 Relationship to Other Micropayment Schemes In this section we compare our proposals to the Millicent[10] NetBill [1] NetCard [2], and Pederson [14] micropayment schemes. NetBill offers a number of advanced features (such as electronic purchase orders and encryption of purchased information) but it is relative expensive: digital signatures are heavily used and the NetBill server is involved in each payment. Millicent uses ....
