SaTC: CORE: Small: A Practical Approach to Study Security in Wireless Networks

随着信息技术部门的快速增长，预计与数据的生成、存储和传输相关的安全挑战将比以往更加普遍。在数据传输的情况下，这就要求为当前和未来的通信网络提供更复杂的安全方案。该项目将为设计跨层安全方案开发一个全面的框架，可以显着提高通信系统的保密性。它促进了传统上孤立的科学领域的合作，包括通信和网络，密码学，信息理论和信号处理。拟议的框架将满足未来网络的各种安全要求，预计将引起学术界和业界的兴趣。除了这些社会和技术贡献，该项目还将通过一些独特的举措促进跨学科的本科生研究机会，并加强本科和研究生水平的课程设置，从而整合研究和教育活动。通过无线通信、网络信息理论和信号处理方面的三位专家的合作，拟议研究项目的总体目标是调查在物理层和应用层考虑的安全措施的相互影响，导致这些层之间更高级别的协作和协调以实现通信的保密性。该项目的具体目标包括：1）研究密码硬度和传输速率之间的相互作用。我们将研究易错密文对密码学的影响，以及它通过传输速率与物理层安全性的相互作用。作为这项研究的结果，加密的硬度和传输速率之间的详细的连接可以表征，并可以实现以上的保密率的传输速率时，提供了一些安全保证的加密; 2）调查有效的防御感知的物理层安全设计通过研究的影响，加密的物理层安全。首先研究了在加密的帮助下传输速率的基本限制，以优化物理层安全性。加密感知的代码设计的秘密，然后调查的帮助下，窃听编码加密时，目前，以增加保密性，和3）调查的联合设计的物理层安全和加密方案之间建立协调。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

With the fast growth of the information technology sector, it is expected that the security challenges associated with generation, storage and transmission of data become even more pervasive than before. In the case of data transmission, this calls for more sophisticated security schemes for the current and future communication networks. This project will develop a comprehensive framework for design of cross-layer security schemes that can significantly enhance the secrecy in communication systems. It fosters collaboration in traditionally isolated areas of science including communications and networks, cryptography, information theory and signal processing. The proposed framework will address the diverse security requirements of future networks and is expected to be of interest of academic community as well as the industry. Besides these societal and technical contributions, this project will also integrate research and education activities by promoting interdisciplinary undergraduate research opportunities via a number of unique initiatives and enhancing the undergraduate- and graduate-level course offerings. The education and outreach activities will additionally broaden the participation of underrepresented groups and female students.Through a collaboration of three experts in wireless communications, network information theory, and signal processing, the overall objective of the proposed research project is to investigate the mutual impact of security measures considered in physical and application layers, leading to a higher level of collaboration and coordination between these layers to achieve secrecy in communication. The specific aims of the project include the following: 1) to investigate the interaction between cryptographic hardness and transmission rate. The impact of error-prone ciphertext to cryptography and its interaction with physical layer security via the transmission rate will be investigated. As a result of this study, the detailed connection between the encryption hardness and transmission rate can be characterized, and the transmission rate above the secrecy rate can be achieved when some security guarantees are provided by the encryption; 2) to investigate efficient encryption-aware physical layer security designs by studying the impact of the encryption on physical layer security. The fundamental limits on the transmission rate under the aid of encryption are first studied to optimize physical layer security. Encryption-aware code designs for secrecy are then investigated under the aid of wiretap coding when encryption is present to increase the secrecy, and 3) to investigate the joint design of physical layer security and encryption schemes by establishing coordination between them. The extension to wireless networks with multiple users and adversaries will also be studied.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
