Combinatorial methods in network security and communication codes

这个项目是我以前的研究工作的延续，由NSERC发现基金支持。在这个项目中，我们将把组合数学应用于计算机网络和通信中的几个重要研究课题。我们将为具有大量实际应用的无线传感器网络提供一些新的安全方案，例如军事传感器网络，检测和描述化学，生物，放射，核和爆炸攻击和材料的传感器网络，检测和监测平原，森林，海洋等环境变化的传感器网络。我们还将提出更有效的传感器网络调度方法，以延长传感器网络的生命周期，提高其可靠性。在通信方面，我们将给出新的光正交码结构，以提供更好的通信性能并支持光网络中大量同时用户。该方案的一个显著特点是组合方法是接近目标的主要工具。本提案致力于通过研究网络安全和通信密码领域的重要课题和培养该领域的高素质青年研究人员，促进网络安全和通信密码领域的组合方法。我们也期待着新的理论和有效的协议的发明来解决这些领域的重要问题。组合数学的理论也得到了进一步的发展。

This project is a continuation of my previous research work that is supported by an NSERC Discovery Grant. In this project, we will apply combinatorial mathematics to several important research topics in computer networks and communications. We will provide some new security schemes for wireless sensor networks that have a lot of real applications, such as military sensor networks, sensor networks to detect and characterize Chemical, Biological, Radiological, Nuclear and explosive attacks and material, sensor networks to detect and monitor environmental changes in plains, forests, oceans, etc. We will also propose more efficient scheduling methods for sensor networks to prolong the lifetime of a sensor network and increase its reliability. For communications, we will give new constructions of optical orthogonal codes, which will provide better communicating performance and support large number of simultaneous users in optical networks. One of the distinctive characteristics of this proposal is that combinatorial methods are the main tools to approach the destination. This proposal is dedicated to promoting the combinatorial methods in network security and communication codes by investigating important topics in these fields and by training highly qualified young researchers in this area. It is also expected that new theories and efficient protocols are invented to solve important problems in these fields. And theories of combinatorial mathematics are further developed as well.
