....for long routes but will make a profit from short routes. The charge n(L # ) and the rewards #(L # ) should thus be set so that relative to the average path length the operator makes the desired profit on average. More details about the averaging principle for micropayments are presented in [26]. 6. SECURITY As we will see in Subsection 6.1, we provide incentives to foster collaboration between rational participants. Furthermore, we design our protocol in a way that it also provides disincentives against cheating (see Subsection 6.2) 6.1 Incentives for collaboration The up stream ....

....device has a threshold determining when they will collaborate. Moreover, there are easier ways of mounting denial of service attacks, such as simply jamming the communication channel. A third component is a technique for aggregation of payments. Similar to the recent proposal by Micali and Rivest [16], this works by a probabilistic selection of payment tokens. As in [16] we allow this aggregation to be performed by the mobile devices (payees) for whom storage is a scarce resource. We also consider aggregation of payment information by the base stations as an additional costsaving measure. To ....

....to an exponential number of random looking bits, which can be of use in protocols. For example, using veri able random functions, one can reduce the number of rounds for resettable zero knowledge proofs to 3 in the bare model [MR01] Another example application, due to Micali and Rivest [MR02], is a non interactive lottery system used in micropayments. Here, the lottery organizer holds a public key PK of a VRF. A participant creates his lottery ticket t himself and sends it to the organizer. The organizer computes the value y = FPK (t) on the lottery ticket, and the corresponding proof ....

....(and proved) VRFs already found several applications. For example, using VRFs one can reduce the number of rounds for resettable zero knowledge proofs to 3 in the bare model [MR01] As another interesting application, they can be used in a non interactive lottery system used in micropayments [MR02] The lottery organizer commits to a VRF by publishing the public key PK . Any participant is allowed to choose his lottery ticket x by himself and send it to the organizer (with the only requirement that x was not used before) The value y = F SK (x) somehow determines whether the user has won ....

....bits, and yet there is a mechanism to convince a third party that all these bits came from the same source. This has proved useful in the design of resettable zero knowledge proof protocols [MR01, Rey01] Another interesting application of veri able random functions, due to Micali and Rivest [MR02] is their use in non interactive lottery systems that in turn are used for micropayments. Here, the lottery organizer holds a public key PK of a VRF. A participant creates his lottery ticket t himself and sends it to the organizer.
