Abstract
Electronic commerce faces the problem of signing electronic contracts. Three approaches for handling electronic contracts include 1) no trusted third party protocols, 2) strongly-trusted third party protocols and 3) weakly-trusted third party protocols. A secondary problem facing electronic commerce is self-enforcing contract design.

Recommendations
A fair protocol for signing contracts
Two parties, A and B, want to sign a contract C over a communication network. To do so, they must simultaneously exchange their commitments to C. Since simultaneous exchange is usually impossible in practice, protocols are needed to approximate ...
Two-round Multi-Party Contract Signing
WKDD '10: Proceedings of the 2010 Third International Conference on Knowledge Discovery and Data MiningA multi-party contract signing (MPCS) protocol allows a set of parties to exchange messages with each other to reach a state in which either each of them has a pre-agreed contract text signed by all the others, or none of them does. A good MPCS protocol ...
A randomized protocol for signing contracts
Randomized protocols for signing contracts, certified mail, and flipping a coin are presented. The protocols use a 1-out-of-2 oblivious transfer subprotocol which is axiomatically defined.
The 1-out-of-2 oblivious transfer allows one party to transfer ...
