This paper presents a password-authenticated hybrid key agreement protocol (PAHKAP) with privacy-privacy to guard security for internet era, which can combine classical cryptography (Chaos Cryptography) and quantum cryptography in a universal way for the most common environment nowadays: Password with two users in two realms. Compared with the former research AQKDPs (authenticated quantum key distribution protocols), PAHKAP have five merits: (1) the basis is dynamic against the long shared key

Moreover, the two-realm architecture can permit any two users to negotiate a fresh session key even if they have registered at the different server. Compared with the related literatures recently, our proposed scheme can not only own high efficiency and unique functionality, but is also robust to various attacks and achieves perfect forward secrecy. Finally, we give the security proof and the comparison with the related works.
