Non-repudiation and fairness turn out to be two important security properties of electronic commerce protocols.In this paper
based on a verifiable encryption with blind decryption
we present a new fair non-repudiation protocol with off-line semi-trusted third party
so either transaction party can unilaterally bring a transaction to completion without losing fairness.This is the first non-repudiation protocol with off-line semi-trusted third party.
