Abstract

Fair exchange between mutually distrusted parties has been recognized as an important issue in electronic commerce. However, the correctness (fairness) of the existing fair exchange protocols that use a Trusted Third Party (TTP) is based on the assumption that during an exchange there are no failures at any of the local systems involved in the exchange, which is too strong in many situations. This paper points out that (1) system failures may cause loss of fairness, and (2) most of the existing fair exchange protocols that use a TTP cannot ensure fairness in presence of system failures. This paper presents two categories of techniques, transaction-based approaches and message-logging-based approaches, to help develop data exchange systems that can recover from system failures without losing fairness.
