组播以其独特的优势，在网络通信方面的应用越来越广泛，但随之而来的就是安全问题，其中密钥管理是最基本的问题之一。本文研究了安全组播中的密钥管理问题。介绍了现有的两种主要解决方案，即SKDC方案和密钥树管理方案，并分析了它们的不足之处，指出基于密钥树的研究方向，在此基础上提出基于Huffman密钥分级树的密钥管理方案，将布尔函数的分析方法运用其中使管理简便化。并对该方案的性能从密钥管理的存储空间和密钥刷新通信量两个方面，给出了相应的分析。-Multicast With its unique advantages in the communication network is widely applied, but the attendant security issues, key management is the most basic one of the problems. This paper studies the security Multicast key management issues. Of the two main existing solutions, and key programs SKDC tree management program analysis of their deficiencies, that the tree on the key directions of research on this basis based on the classification tree Huffman key Key Management Program, Boolean function of the analytical method which enable the use of simple. Program and the performance of key management from the storage space and traffic Key set two, given the corresponding analysis.

有许多应用程序创建的线程花费了大量时间在睡眠状态来等待事件的发生。还有一些线程进入睡眠状态后定期被唤醒以轮询工作方式来改变或者更新状态信息。线程池可以让你更有效地使用线程，它为你的应用程序提供一个由系统管理的工作者线程池。至少会有一个线程来监听放到线程池的所有等待操作，当等待操作完成后，线程池中将会有一个工作者线程来执行相应的回调函数。-thinks

一本介绍VerilogHDL硬件描述语言的中文版简明教程，-VerilogHDL introduce a hardware description language of the Chinese version of A Concise Guide,

the book provides many solved examples that illustrate the principles involved, and includes, in addition, two chapters that deal exclusively with applications of unconstrained and constrained optimization methods to problems in the areas of pattern recognition, control systems, robotics, communication systems, and the design of digital filters. For each application, enough background information is provided to promote the understanding of the optimization algorithms used to obtain the desired solutions.
