The project aims at quantifying a general network's inner potentialfor supporting various forms of security by achieving secret commonrandomness between pairs or groups of its nodes. Statistical andcomputational secrecy measures are being considered against a generalpassive adversary. Common-randomness-achieving protocols are classifiedinto two groups: culture-building and crowd-shielding. The former achievescommon randomness between nodes situated in close proximity of each other,from correlated observations of specific (natural or induced) networkphenomena. The latter ties together the security of multiple communicationlinks, to the point where an adversary can no longer isolate and attacka single link without attacking the group as a whole. The broad range ofinvestigated protocols cover multiple topics, from multipath diversityto network tomography, from secure network coding to protocol coding,and from anonymous routing to the spread of epidemics. The protocolsharvest network randomness from diverse sources like ciphertext blocksoriginating at various terminals, contention protocols (delay randomness)or network topology (in highly-dynamic, or ad-hoc networks).Communication networks are naturally dynamic, inherently redundant,and largely unpredictable. While the former two features have longbeen recognized as a valuable resource for integrity, efficiencyand confidentiality, network unpredictability is often regarded as anincommodity. This project shows how network randomness can be harvested,and, together with diversity, exploited to enhance communicationsecurity. In doing so, it develops a more profound understanding aboutthe statistical nature of networks, which can be applied to a broad rangeof information-assurance objectives. The technical approaches and thegeneral philosophy developed in this project, and disseminated throughconferences and seminars, have the potential to inspire an abundance ofrelated research. The project will directly impact dozens of studentsthrough Senior Design projects, a research-and-open-project approach tocurriculum development, and three new graduate courses containing relatedtopics. The PIs are actively involved in programs aimed at increasingthe involvement of women, underrepresented minorities, and persons withdisabilities in engineering and computing sciences.

该项目旨在量化通用网络的内部潜力，从而通过在对或群体的群体之间实现秘密的共同点来支持各种形式的安全性。 统计和计算保密措施被视为一般的对手。共同方面的协议分为两个群体：文化建设和人群园艺。前者从相关的（自然或诱导）网络的相关观察结果彼此紧密近端达到了彼此近距离的节点之间的随机性。后者将多个通信链接的安全性联系在一起，以至于在不攻击整个小组的情况下，对手无法再隔离并攻击单个链接。广泛的评估协议范围涵盖了从安全网络编码到协议编码到协议编码，从匿名路由到流行病的传播的多个主题。 从各种来源（如密封文本封锁）在各种终端，争夺协议（延迟随机性）或网络拓扑（以高度动态或临时网络）（以高度动态或临时网络为单位）等各种来源的协议收获网络随机性。通用网络自然动态，本质上是固有的，固有的，并且很大程度上是毫无疑问的。尽管前两个功能已被认为是完整性，效率和机密性的宝贵资源，但网络不可预测性通常被视为商品。该项目显示了如何收获网络随机性，并与多样性一起利用以增强通信性。通过这样做，它对网络的统计性质有了更深刻的理解，可以应用于广泛的信息 - 信息实现目标。 该项目在该项目中发展的技术方法和通用哲学，并通过会议和研讨会传播，有可能激发很多相关的研究。该项目将直接影响数十个高级设计项目，研究和开幕的方法开发以及三个包含相关文学的新研究生课程。 PI积极参与旨在增加妇女参与，代表性不足的少数群体以及在工程和计算科学领域的人员的参与的计划。
