The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project results from a new capability to detect eavesdropping on a fiber optic data communications link. Much of human society - commerce, social interaction, entertainment, etc. - is increasingly information-based. Technology related to the production and dissemination of information is developing at an exponential rate, with optical communications systems in particular forming the backbone of the internet and other high-capacity communications networks. It is little wonder, therefore, that the wealth of modern society is increasingly represented in the form of information. Protecting such information from access by unauthorized persons or entities is obviously of increasing importance across all sectors of society. This project is aimed at developing a technology to detect the leakage of information at the physical layer in an optical communications system, thus detecting intrusion by an unauthorized party.This Small Business Innovation Research (SBIR) Phase I project brings innovation in securing fiber optic physical transmission media by developing a novel polarization-based intrusion detection system and demonstrating its commercial value. Secure transmission of data is critical to governments, military organizations, financial institutions, health care providers and other enterprises. The proposed fiber optic polarization-based intrusion detection system utilizes the properties of light, as they are manifested in single mode fiber, as a means of ensuring the integrity and security of the physical layer of a fiber-optic based communication link. This technology breakthrough is expected to provide a low-cost means for operators of fiber optic systems to detect intrusion and take corrective measures. Since single mode optical fibers are the primary transmission media of high-capacity long distance telecommunications networks, the proposed technology will enable the detection and prevention of potentially one of the most damaging forms of information theft.

这一小型企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力来自于检测光纤数据通信链路窃听的新能力。人类社会的许多方面--商业、社会交往、娱乐等--越来越以信息为基础。与信息生产和传播有关的技术正在以指数速度发展，特别是光通信系统构成了互联网和其他高容量通信网络的骨干。因此，毫不奇怪，现代社会的财富越来越多地以信息的形式出现。保护此类信息不被未经授权的个人或实体获取，显然对社会各部门越来越重要。本项目的目的是开发在光通信系统的物理层检测信息泄漏的技术，从而检测非法入侵者。SBIR（Small Business Innovation Research）第一期项目通过开发基于偏振的新型入侵检测系统，在光纤物理传输介质的安全性方面进行创新，并展示其商业价值。数据的安全传输对政府、军事组织、金融机构、医疗保健提供商和其他企业至关重要。所提出的基于光纤偏振的入侵检测系统利用光的特性，因为它们在单模光纤中表现出来，作为确保基于光纤的通信链路的物理层的完整性和安全性的手段。这一技术突破有望为光纤系统运营商提供一种低成本的手段，以检测入侵并采取纠正措施。由于单模光纤是大容量长距离电信网络的主要传输介质，因此所提出的技术将能够检测和预防潜在的最具破坏性的信息盗窃形式之一。
