Key agreement is a crucial cryptographic primitive for building secure communication channels between two parties in a network. In the research literature a typical protocol aims for key secrecy and mutual authentication. However, there are many important practical scenarios where privacy protection is more desirable, especially for social network. Network privacy security means that the personal data and online data are not peep, intrusion, interference, illegal collection and utilization. In our paper, we propose a robust chaotic maps-based authentication key agreement scheme with privacy protection using smart cards. The key idea of our proposed scheme is to adopt chaotic maps for mutual authentication, not to encrypt/decrypt messages transferred between user and server, which can make our proposed scheme much more efficient. Next, we give the formal provable security under the random oracle model for our scheme. Finally, our proposed scheme can not only achieve privacy protection, but also avoid time-consuming modular exponentiation and scalar multiplication on elliptic curves. Meanwhile, it can resist various common attacks, and provide prefect forward secrecy and known-key secrecy. In brief, compared with related schemes, our proposed scheme is more secure, effective and practical.
