Towards a Secure Data Stream Management System
نویسندگان
چکیده
Todays data stream management systems (DSMSs) lack security functionality. Based on adversary scenarios we show how a DSMS architecture can be protected. We sketch a general DSMS architecture and introduce security issues that need to be considered. To face the threats we develop an extended system architecture that provides the necessary security mechanisms. We descuss the chosen concepts and illustrate how they can be realized by various system components. Our design focus is, considering the unique properties of data stream engines, to keep the impact on existing system components as little as possible and to limit the effect on the overall performance to a minimum.

Multilayer multicast key management with threshold cryptography
The problem of distributing multimedia securely over the Internet is often viewed as an instance of secure multicast communication, in which multicast messages are protected by a group key shared among the group of clients. One important class of key management schemes makes use of a hierarchical key distribution tree. Constructing a hierarchical tree based on secret shares rather than keys yie...
متن کاملMultilevel secure data stream processing: Architecture and implementation
The proliferation of sensors and mobile devices and their connectedness to the network have given rise to numerous types of situation monitoring applications. Data Stream Management Systems (DSMSs) have been proposed to address the data processing needs of such applications that require collection of high-speed data, computing results on-the-fly, and taking actions in real-time. Although a lot ...

Data Stream Management Systems (DSMSs) have been proposed to address the data processing needs of such applications that require collection of high-speed data, computing results on-the-fly, and taking actions in real-time. Although a lot of work appears in the area of DSMS, not much ha...
متن کاملTowards Secure Cloud Data Management
This paper explores the security challenges posed by data-intensive applications deployed in cloud environments that span administrative and network domains. We propose a data-centric view of cloud security and discuss data management challenges in the areas of secure distributed data processing, end-to-end query result verification, and cross-user trust policy management. In addition, we descr...
