| 摘 要： | A new class of atomicity, namely contract atomicity is presented. A new technical strategy based on convertible signature and two-phase commitment is proposed for implementing atomicity of electronic contract protocol. A new atomic contract signing protocol is given out by using EIGamal like convertible undeniable signature and commitment ofconversion key, and another new atomic contract signing protocol is brought forward by using RSA based convertible undeniable signature scheme and commitment of conversion key. These two new protocols are proved to be of atomicity, fairness, privacy, non repudiation.
