The objective of this research is to address the challenge in trustworthy sensing and communications, as content-rich audio-visual streams become increasingly adapted on-the-fly for individual receivers. The proposed project develops a novel framework of Forensic Hash for Information Assurance (FASHION) in sensing and communications. The framework utilizes a strategically designed compact string and the associated decision mechanism to transcend the capabilities of conventional hash and non-intrusive forensics. Offering more forensic answers about data integrity, origin, and processing history in higher accuracy and efficiency, the proposed framework overcomes the current one-size-fit-all dilemma to enable trust assessment to a high level. The main investigations include: what evidentiary information to form forensic hash; theories and algorithms on how to compactly and securely encode forensic hash, and robustly and securely associate it with source data; attack strategies and counter-attacks; and developing a Testbed for experimental evaluation of the proposed framework.The intellectual merit lies in exploring the unchartered area of Information Forensic Hash that transcends from prior art, advancing theories and algorithms of assured cyber sensing and communications, and providing new capabilities and tools to the community. In particular, the proposal leverages recent advances in non-intrusive forensics to add flexibility and reveal richer information for trustworthiness assessment of cyber-based sensing and communications. The proposed research has the potential to open a new research area in information forensics which is very relevant to the health and development of the cyber-infrastructure.The proposed research, if successful, could have significant impact on many applications of national interests, including the US IT infrastructure, as sensing and communicating audio-visual data have become a central part in government operations and in services by the high-tech industry, whose continuing success is critical to U.S.'s economic prosperity. The broader impact comes from the seamlessly integration of research with education/outreach through the framework's Testbed and special honor programs, to actively attract and nurture under-represented students to develop a successful engineering career.

这项研究的目的是应对值得信赖的感应和通信的挑战，因为内容丰富的音频流越来越适合单个接收器。拟议的项目开发了一个新颖的法医哈希框架，以进行信息保证（时尚）。该框架利用战略性设计的紧凑型字符串和相关的决策机制超越了常规哈希和非侵入性取证的能力。提出的框架提供了有关数据完整性，来源和处理历史记录历史记录的更多法医答案，该框架克服了当前的一定大小的所有困境，以使信任评估能够高水平。主要调查包括：构成法医哈希的哪些证据信息；关于如何紧凑，安全地编码法医哈希的理论和算法，并将其与源数据牢固并牢固地关联；攻击策略和反击；并开发了用于对拟议框架的实验评估的测试床。智力优点在于探索超越先前艺术的信息法医哈希的未包含的信息领域，从而推进了确保的网络感应和交流的理论和算法，并为社区提供新的功能和工具。尤其是，该提案利用了非侵入性取证的最新进展来增加灵活性，并揭示了更丰富的信息，以评估基于网络的感应和通信。拟议的研究有可能在信息取证方面开放新的研究领域，该研究与网络基础设施的健康和发展非常相关。拟议的研究（如果成功）可能会对许多国家利益的应用产生重大影响，包括美国IT基础设施，包括感应和交流的企业在政府中的企业中的中央繁荣和统一的效果，其在较高的领域中，其较高的企业在较高的领域中占有一定的努力，其在较高的领域中一直在延续了高级领域的行业。更广泛的影响来自通过框架的测试床和特殊荣誉计划将研究与教育/宣传无缝整合，以积极吸引和培育不足的学生来发展成功的工程职业。
