A three-party quantum key agreement protocol based on EPR pairs is proposed, in which the three participants have equal status in the protocol and each participant is capable of contributing to the shared secret key in the same degree. In addition, any one or two parties cannot predetermine the value of shared key alone. The security analysis shows that our protocol can resist the outside attack and the dishonest participants attack.
