项目摘要

As wireless networks become ubiquitous, the ability to maintain trust and securely exchange confidential information among interconnected wireless devices and users is crucial. Secret sharing is a cryptographic primitive that can help to achieve secure communication with applications that include access control, key management, digital signatures, and others. Although this primitive is widely used, it is still not fully understood how wireless communication constraints such as noise, limited bandwidth, and scalability can be optimally accounted for in the design of secret sharing schemes. This project aims for new guidelines for the implementation of secret sharing directly adapted to wireless communication constraints, to improve security for users, minimize the communication cost associated with the implementation, and facilitate deployment in dense wireless networks through improved scalability.Most existing secret sharing schemes hinge on the assumption that the dealer can securely communicate the shares of the secret to the participants over noiseless channels with unlimited bandwidth. Under such an assumption, the implementation of secret sharing schemes in wireless networks requires additional layers of protocols able to deal with unsecured, noisy, and bandwidth limited communication channels between the dealer and the participants. The objective of this project is to understand whether such a layered approach is optimal and whether a scheme that simultaneously addresses the constraints of wireless communication and the requirements of secret sharing could provide gains in terms of communication efficiency and security guarantees. The project investigates two interdependent research tasks: (i) understanding the fundamental security limits for secret sharing in wireless networks under bandwidth constraints and noise, and (ii) the design of explicit low-complexity coding schemes using tools from cryptography and coding theory.This award is jointly funded by the Division of Computing and Communication Foundations in the Directorate for Computer & Information Science & Engineering and the Established Program to Stimulate Competitive Research in the Office of Integrative Activities.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.

随着无线网络无处不在，在互连的无线设备和用户之间保持信任并安全地交换机密信息的能力至关重要。秘密共享是一个加密原始的原始性，可以帮助与包括访问控制，密钥管理，数字签名等的应用程序进行安全沟通。尽管这种原始性被广泛使用，但仍未完全了解如何在秘密共享方案的设计中最佳地解释噪声，有限的带宽和可伸缩性等无线通信约束。 This project aims for new guidelines for the implementation of secret sharing directly adapted to wireless communication constraints, to improve security for users, minimize the communication cost associated with the implementation, and facilitate deployment in dense wireless networks through improved scalability.Most existing secret sharing schemes hinge on the assumption that the dealer can securely communicate the shares of the secret to the participants over noiseless channels with unlimited bandwidth.在这样的假设下，无线网络中秘密共享方案的实施需要其他能够处理经销商与参与者之间无抵押，嘈杂和带宽有限的通信渠道的协议层。该项目的目的是了解这种分层方法是否是最佳的，以及同时解决无线通信限制的计划以及秘密共享的要求是否可以为通信效率和安全保证提供的收益。 The project investigates two interdependent research tasks: (i) understanding the fundamental security limits for secret sharing in wireless networks under bandwidth constraints and noise, and (ii) the design of explicit low-complexity coding schemes using tools from cryptography and coding theory.This award is jointly funded by the Division of Computing and Communication Foundations in the Directorate for Computer & Information Science & Engineering and the Established Program to Stimulate Competitive Research in综合活动办公室。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评论标准来评估值得支持的。
