S.N. Foley, T.B. Quillinan. Using Trust Management to Support MicroPayments, In proceedings of the Annual Conference on Information Technology and Telecommunications, Waterford, Ireland, October 2002.


This paper illustrates how hash-chain based micropayment schemes can be codified within the KeyNote Trust Management system. We describe an application of this scheme to the secure WebCom system, a distributed computation architecture. This supports micropayments made by servers to clients for computations performed and, payments by clients to servers for services.
