To avoid this problem, we propose an evenhanded certified email system in which each participant can change his/her choice, either cancel or finish the transaction, at any time during the transaction.

Efficient ID-Based Optimistic Fair Exchange with Provable Securityproof is needed to provide verifiability. The proposed optimistic fair exchange protocol is much concise and efficient, and can be shown to be secure in the random model with a tight security reduction.
