用户认证是无线传感器网络中的一个重要问题。Das等人最近提出了一种基于动态口令的分层无线传感器网络用户认证方案，该方案提供了高安全性和简单的认证方法。在本文中，我们提出了一个缺陷达斯等人。的计划，使其不可行的现实生活中的实施。此外，我们证明，达斯等人。的方案存在冗余元素。为了克服这些缺陷，我们提出了一个增强的用户认证方案的基础上Das等人。的，既高效又安全。
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.'s scheme that makes it infeasible for real-life implementation. Additionally, we demonstrate that Das et al.'s scheme has redundant elements. To overcome these imperfections we propose an enhanced user authentication scheme based on Das et al.'s, which is both efficient and secure.
