Secure infromation transmission and data storage in distibuted systems

大量无处不在的无线通信设备和分布式数据库的部署提供了新的机遇和挑战。在这个范例中，用户可以使用他们的手机或pda来形成临时网络。他们将利用自己的生物特征相互验证自己，并访问由传感器网络收集的信息，这些信息存储在传统和新型网络的分布式数据库中。建议的研究将在这样一个范例中解决安全问题。它包括安全、分布式数据库和信息系统三个主要领域的问题研究。首先，我们感兴趣的是与如何在分布式系统（如传感器和自组织网络）中收集信息相关的安全问题。其次，我们将研究如何在分布式数据库上安全地存储和检索信息。第三，我们将研究使用生物识别密码系统和资源约束设备进行安全信息访问。

Deployment of large numbers of ubiquitous wireless communication devices, and distributed databases offers new opportunities and challenges. In this paradigm, users may use their cellphones or PDAs to form impromptu networks. They will authenticate themselves to each other using their biometric traits, and access information gathered by a network of sensors and stored on distributed databases across conventional and new types of networks. The proposed research will address security issues in such a paradigm. It is comprised of the study of problems in three main areas of secure, distributed database and information systems. First, we are interested in security issues related to how information is gathered in distributed systems such as sensor and ad hoc networks. Second, we will examine how information is stored and retrieved securely over distributed databases.  Third, we will study the use of biometric cryptosystems and resource constraint devices for secure information access.
