A Randomized Protocol for Signing Contracts

  • Conference paper

Abstract

Suppose two parties A, and B, in a communication network, have negotiated a contract, which they wish to sign. To this end, they need a protocol which has the two following properties:

  1. (1)

    At the end of an honest execution of the protocol, each party has a signature of the other.

  2. (2)

    If one party, X, executes the protocol honestly, his counterpoint, Y, cannot obtain X’s signature to the contract without yielding his own signature.
