Collaborative Research: Efficient Data Distribution Schemes for Secure and Reliable Networked Storage Systems

无处不在的计算的兴起促使我们需要改变存储和获取信息的方式。它要求研究在广域网上分发信息的数据存储系统，使用户能够以持续可用和高度可信的方式存储和访问关键数据。研究了数据分布问题，即在实现数据可靠性、保密性和性能的同时，将数据存储在网络存储系统中。研究了基于（n,k）个纠错码的数据分发方案。研究将集中在两个关键问题上：1)如何在分布式网络环境中存储数据时实现强大且计算效率高的数据加密？2)在考虑网络拓扑结构的同时，如何将编码数据段放置在网络系统中，以实现高性能和可靠的数据检索？本研究项目的见解和成果将为有线和无线网络高效、安全、可靠的数据分发方案提供指导，并对密码学、编码理论、图论和组合学等相关理论研究做出重要贡献。此外，将努力将这项研究计划纳入教育活动。

The rise of ubiquitous computing has prompted the need for a change in the way we store and access information. It calls for the study of data storage systems that distribute information over wide area networks, enabling users to store and access critical data in a continuously available and highly trustable fashion. The problem of data distribution, i.e., storing data in networked storage systems while achieving data reliability, confidentiality and performance is studied.Data distribution schemes based on (n,k) error correcting codes are investigated. The research will focus on two key questions: 1) how to achieve strong and computationally efficient data encryption while storing data over a distributed networked environment? and 2) how to place encoded data segments in networked systems, while considering the structure of the network topology, to enable high performance and reliable data retrieval? Insights and results from this research program will provide guidelines for efficient, secure and reliable data distribution schemes for wired and wireless networks, as well as make significant contributions to related theory study, such as cryptography, coding theory, graph theory and combinatorics. In addition, efforts will be made to integrate this research program into educational activities.
