This work aims to effectively address security concerns while maintaining the privacy of individuals and corporations. The project analyzes subversive attacks, develops defenses and deterrents, creates privacy tools and software, and increases awareness and expertise through teaching, mentoring and involvement of students in research. This research rethinks the basics of cryptographic security to provide new models, frameworks, tools and solutions. This project considers the subversion of random number generators and offers forms of encryption that are robust in its presence. The project explores: (1) the subversion of certificate authorities and offer certificate-signing mechanisms that deter it, (2) the exfiltration of cryptographic keys by malware installed on systems and development of big-key cryptography as a deterrent, and (3) the subversion of key distribution protocols through infiltration of their endpoints and development of new protocols to resist it.

这项工作旨在有效解决安全问题，同时维护个人和企业的隐私。该项目分析颠覆性攻击，开发防御和威慑手段，创建隐私工具和软件，并通过教学、指导和学生参与研究来提高意识和专业知识。这项研究重新思考了密码安全的基础知识，以提供新的模型、框架、工具和解决方案。该项目考虑了随机数生成器的颠覆，并提供了稳健的加密形式。该项目探讨：（1）颠覆证书颁发机构并提供阻止它的证书签名机制，（2）通过系统上安装的恶意软件渗透加密密钥并开发大密钥加密技术作为威慑手段，以及（3）通过渗透其端点并开发新协议来抵抗密钥分发协议。
