A great deal of password authenticated key exchange (PAKE) protocols have been proposed in recent years. Most of them were based on Diffie-Hellman key exchange. While the approach of designing PAKE protocols with RSA is far from maturity and perfection. In fact, the existing PAKE protocols using RSA or other public-key cryptographic techniques provide an authenticated key exchange only between a client and a server. This paper presents a new efficient PAKE protocol using RSA in the three-party settings (3PAKE-RSA). The novel protocol can be resistant to e-residue attack and provably secure under the RSA assumption in the random oracle model.
