Non-repudiation service is crucial to electronic commerce. We have made some research of ATL logic method and its applications in multi-party security protocols formalized analysis. A typical multi-party non-repudiation protocol is modeled and analyzed by using ATL logic and MOCHA, and discovered that it existence a unfair flaw. We have improved this multi-party non-repudiation protocol by add the time limit to each participant, and enable it to have the timeless and fairness simultaneously.
