CAREER: Practice-oriented provably secure information hiding

Nicholas Hopper Minnesota-Twin Cities 0546162摘要信息隐藏协议试图减轻加密无法防止的信息泄漏：隐写协议试图在无辜的消息中隐藏敏感的通信，匿名协议试图隐藏消息的真实发送者和接收者，水印或指纹协议试图不可磨灭地标记对象以允许跟踪泄漏。目前的信息隐藏理论与实践之间存在着差距，使得目前使用的系统容易受到个人信息泄漏的影响。本项目的重点是应用最新开发的密码技术来开发和实现有效且可证明安全的信息隐藏协议。 该项目的第二个重点是应用密码证明技术来提高对隐写术、水印和匿名协议之间的关系和固有局限性的理解。该项目预计将通过改善对个人隐私、国家安全和知识产权的保护，产生对社会有直接好处的协议。 此外，这项工作的一个重要贡献是正在开发的理论攻击模型，预计将反馈到未来协议的评估，加强信息隐藏研究的基础设施。

Nicholas HopperMinnesota-Twin Cities0546162AbstractProtocols for Information Hiding attempt to mitigate information leakage that encryption cannot prevent: steganography protocols attempt to conceal sensitive communication within innocent messages, anonymity protocols attempt to conceal the true sender and recipient of messages, and watermarking or fingerprinting protocols attempt to indelibly mark objects to allow tracing of leaks. A gap exists between current theory and practice of information hiding, leaving currently used systems vulnerable to leakage of personal information.This project is focused on applying recently developed cryptographic techniques to develop and implement efficient and provably secure protocols for information hiding. A secondary focus of the project is applying cryptographic proof techniques to improve understanding of the relationships between, and the inherent limitations of, steganography, watermarking, and anonymity protocols.The project is expected to produce protocols that exhibit direct benefits to society, by improving the protection of personal privacy, national security, and intellectual property. Furthermore, an important contribution of this work is the theoretical attack models under development, which are expected to feed back into evaluation of future protocols, enhancing the infrastructure for research in information hiding.
