User authentication is an important issue in wireless sensor networks. Das et al. recently proposed a dynamic password-based user authentication scheme for hierarchical wireless sensor networks, which provides high security and a simple authentication approach. In this paper we present a flaw in Das et al.%26apos;s scheme that makes it infeasible for real-life implementation. Additionally, we demonstrate that Das et al.%26apos;s scheme has redundant elements. To overcome these imperfections we propose an enhanced user authentication scheme based on Das et al.%26apos;s, which is both efficient and secure.
