Abstract

We show a novel application of cryptography and implement the first sealed bargain scheme. Beginning with the conventional bargain, we define a sealed bargain model. Compared with the conventional bargain, the sealed one enjoys more convenience without loss of its economic properties. Finally, a concrete and simplified sealed bargain scheme is proposed with protection of privacy of both the seller and the costumer. The scheme follows the buy-and-leave principle, and one round of communication are sufficient. Pre-calculations can also be performed to improve practicality.
