中文摘要：

ZigBee技术作为无线传感网络领域的新兴技术获得广泛应用，其安全性日益重要。本文从现存的ZigBee安全体系入手，针对ZigBee的安全结构、安全服务、安全模式、安全组件、安全密钥和信任中心以及各层的安全措施展开论述，并具体介绍了ZigBee实现安全的步骤，最后提出一种可以提高ZigBee安全性的密钥管理方案的新思路。

英文摘要：

ZigBee, an emerging wireless sensor,network technology, has wide application and its security is increasingly significant. This paper presents its security architecture, security service, security model, security components, security keys and trust center and security policy of each layer. The paper also gives its security implementation steps. The paper eventually proposes a new idea for its key management, which is favorable to its security enhancement.
