Excellence in Research: Parallel Linear Feedback Shift Register Based Encryption on Commodity Systems

这项研究是为了促进计算机安全方面的知识，因为它与蜂窝电信和图像加密有关。当前的数字革命和无处不在的移动技术以及社交媒体使用量的激增带来了严重的安全挑战。这个项目就是为了应对这些挑战而设计的。这项研究将加强移动设备的通信渠道，以确保对话安全，确保数据免受拦截，并防止发生手机欺诈。该国的移动网络有两个突出的标准，它们是全球移动通信系统和码分多址。虽然后者在美国被广泛使用，但前者已经成为全球网络的事实上的标准，其用户在2017年超过50亿。据估计，这一数字将在未来十年内增加到57亿用户。这种快速增长带来了安全问题，本项目通过开发和分析具有成本效益和效率的加密算法来解决这些问题。研究的结果和结论将通过印刷媒体、专业会议、研讨会和讲习班广泛传播。将从该研究项目开发的软件将公开提供。来自科学、技术、工程和数学领域中代表性不足的少数群体的本科生将学习信息安全研究。总体而言，这项研究的产品将在安全移动通信、图像加密和费耶特维尔州立大学(一所历史上的黑人学院，北卡罗来纳大学系统的17所组成机构之一)的信息安全研究发展领域为社会带来深远的好处。通过移动通信渠道传输的加密数据可能容易受到加密攻击，因为恶意代理可能会通过运行可以破坏加密数据安全性的算法来窃取机密信息。通过加密和解密的组合(称为密码)来安全地传输数据是解决移动通信中这一问题的一般方法。具体地说，与其他密码相比，流密码不会受到传播错误的影响，并且它们往往具有更好的软件效率。本研究的重点是移动通信和图像加密的应用，流密码通常是这些应用的典型选择。研究将涉及流密码的许多方面，特别是基于线性反馈移位寄存器的流密码及其与二进制本原多项式和矩阵运算的关系。该项目将包括开发用两种主要计算机编程语言编写的综合软件库；基于流的算法的比较复杂性和安全性分析；应用图形处理单元集群对基于计算统一设备架构编程的算法进行密码分析；让本科生参与真实研究；以及在费耶特维尔州立大学建设信息安全研究能力。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This research is an effort to advance knowledge in computer security as it relates to cellular telecommunications and image encryption. The present digital revolution with the ubiquitous mobile technologies and the surge in social media usage raise serious security challenges. This project is designed to address such challenges. The research will strengthen mobile device communication channels in order to secure conversations, ensure that data is protected from interception, and prevent cellular fraud from occurring. There are two prominent standards for mobile networks in the country, and they are the Global System for Mobile Communications and the Code Division Multiple Access. While the latter is widely used in the United States, the former has become the de-facto standard for global networks with its subscribers surpassing five billion in 2017. It is estimated that this number will increase to 5.7 billion subscribers within the next decade. This rapid growth brings with it security concerns that are addressed in this project through the development and analyses of cost effective and efficient encryption algorithms. The results and findings of the research will be widely disseminated through print media, professional conferences, seminars, and workshops. The software that will be developed from this research project will be made publicly available. Undergraduate students from under-represented minority groups in Science, Technology, Engineering and Mathematics will be exposed to research in information security. Overall, the products from this research will have far reaching benefits to the society in areas of secure mobile communications, image encryption and the development of information security research at Fayetteville State University (a historically black college and one of the seventeen constituent institutions in the University of North Carolina System).Encrypted data transmissions through mobile communication channels are potentially vulnerable to cryptographic attacks since malicious agents may steal confidential information by running algorithms that can break the security of the encrypted data. Secure transfer of data through the combination of encryption and decryption, known as cipher, is the general approach to solving this problem in mobile communications. Specifically, stream ciphers do not suffer from propagation errors compared to other ciphers, and they tend to have better software efficiency. This research is focused on the applications of mobile communications and image encryption for which stream ciphers are often the typical choice. The research will span many aspects of stream ciphers, particularly Linear Feedback Shift Registers-based stream ciphers and their relationships to binary primitive polynomials and matrix operations. The project will include development of comprehensive software libraries written in two prominent computer-programming languages; comparative complexity and security analysis of algorithms that are stream-based; application of Graphics Processing Unit clusters for cryptanalysis of algorithms based on Compute Unified Device Architecture programming; engagement of undergraduate students in authentic research; and building research capacity in information security at Fayetteville State University.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.
