CT-ER: Secure Communication System Design for Wireless Networks

该项目旨在通过严格的安全访问控制和强大的隐私保护，为固有安全的无线网络开发先进的设计方法。首先，对于安全访问控制，它建立了一个弹性和高可靠的无线接口，以高度安全的基于用户的访问控制来加强或取代目前基于设备和/或基于密码的安全性。主要的挑战在于基于用户的访问控制通常需要比传统的用户验证过程多几个数量级的可靠传输。本课题设计了弹性安全协议和高容量访问控制协议，以实现有效的凭证信息传输和实时用户认证。其次，在现有的隐私保护方案中，信息保密主要是在网络层进行的，与物理层无关，远远不能满足多媒体无线通信的需要。本研究通过将加密技术集成到收发器设计中来提高物理层的内置安全性。本项目基于加密技术和多接入信道信号检测固有的模糊性，制定了物理层和上层联合隐私保护机制。最后，整个系统的集成和验证将通过一个可重构的仿真平台进行。通过直接解决多个关键的无线安全问题，预计在该项目中实现的重要技术进步将为新一代高度安全无线网络的设计和开发做出重大贡献。此外，通过将技术进步整合到本科/研究生课程中，并通过外展活动，预计该项目将对在无线通信和网络安全领域培训高技能和多样化的劳动力产生重大影响，并对公众进行有关无线通信安全和道德操作需求的教育。

Proposal: 0716039Tontong Ellen LiCT-E: Secure Communication System Design for Wireless NetworksMichigan State UniversityThis project aims to develop advanced design methodologies for inherently secure wireless networks through tight secure access control and strong privacy protection. First, for secure access control, it establishes a resilient and highly reliable wireless interface to strengthen or replace the current device-based and/or password-based security by the highly secure user-based access control. The major challenge lies in that user based access control generally requires reliable transmission of several orders of magnitude more bits than the traditional user verification process. In this project, resilient security protocols and high capacity access control protocols are designed for effective credential information transmission and real time user authentication. Second, in current privacy protection schemes, information confidentiality is mainly performed at the network layer independent of the PHY layer, and thus is far from adequate for multimedia wireless communications. This research enhances the PHY layer built-in security by integrating cryptographic techniques into the transmitter-receiver design. Based on both cryptographic techniques and inherent ambiguity in signal detection over multiple access channels, this project formulates a joint PHY layer and upper layer privacy protection mechanism. Finally, overall system integration and validation will be performed through a reconfigurable simulation platform. By directly addressing multiple pivotal wireless security concerns, it is anticipated the important technological advances to be achieved in this project will contribute significantly to the design and development of a new generation of highly secure wireless networks. Additionally, by integrating the technological advances into the undergraduate/graduate curricula, and through outreach activities, significant impacts are expected from this project on training a highly-skilled and diverse workforce in the areas of wireless communications and network security, and on educating the public with respect to the need for secure and ethical operations in wireless communications.
