Abstract: Electronic transaction becomes common practice in real world business. This paper focuses on the issue of dependability in critical transactions like electronic payment, electronic contract signing. Recent fair protocols can recover transactions from network crashes, but cannot survive local system crashes. A two-party dependable transaction protocol is proposed. During the protocol, both parties can recover the transaction from network and local system failures in a transparent way, which means that after the recovery, outcome messages would be just the same as those from a successful run of the transaction.
