近年来，通信网络的普及加速了无线网络和互联网应用的发展。除了电信企业提供的公共服务外，如何将一些不同的用户连接起来，形成一个网络，让他们处理自己的工作，也是许多学者研究的热门话题（Eskeland and Oleshchuk，2007；Sun and Liu，2007；Tzeng，2006）。在网络建设中，密钥管理是各个系统要解决的首要问题。有许多非分层的密钥协商协议。然而，等级制度在我们的现实生活中无处不在。在本文中，我们使用椭圆曲线密码学和双线性映射函数实现了可验证的分层密钥派生方案，与RSA系统相比，该方案可以达到相同的安全级别但使用更少的位数。
In recent years, the ubiquity of communication networks speeds up the development of wireless network and the internet applications. In addition to the common service provided by the telecommunication enterprise, how to connect some distinct users to form a network which allow them to deal with their own works is a popular topic that many scholars engage in (Eskeland and Oleshchuk, 2007; Sun and Liu, 2007; Tzeng, 2006). When constructing the network, the key management is the most important problem that each system has to solve. There are many key agreement protocols which are non-hierarchical. However, the hierarchy is ubiquitous in our real life. In this paper, we have achieved a verifiable hierarchical key derivation scheme using the elliptic curve cryptography and the bilinear mapping function which can achieve the same security level but use less bit number when comparing to the RSA system.
