Remote user authentications are an essential tool for e-commerce in Internet environment. In these systems, identity privacy is provided by concealing user's identity. In this article, we introduce the identity privacy study of this setting, and explore a secure and efficient dynamic ID-based remote user authentication protocol with untraceability. We adapt a pair of dynamic IDs to realize the user's anonymity, and present a novel nonce-based authentication approach. Our protocol eliminates all identified security flaws in original protocols. Furthermore, high performance and other good functionalities are preserved.
