a survey on the application of fpgas for Network Infrastructure security
IEEE Communications Surveys and Tutorials, 2011Co-Authors: Hao Chen, Yu Chen, Douglas H SummervilleAbstract:Given the rapid evolution of attack methods and toolkits, software-based solutions to secure the Network Infrastructure have become overburdened. The performance gap between the execution speed of security software and the amount of data to be processed is ever widening. A common solution to close this performance gap is through hardware implementation of security functions. Possessing the flexibility of software and high parallelism of hardware, reconfigurable hardware devices, such as Field Programmable Gate Arrays (FPGAs), have become increasingly popular for this purpose. FPGAs support the performance demands of security operations as well as enable architectural and algorithm innovations in the future. This paper presents a survey of the state-of-art in FPGA-based implementations that have been used in the Network Infrastructure security area, categorizing currently existing diverse implementations. Combining brief descriptions with intensive case-studies, we hope this survey will inspire more active research in this area.

Virtualized Network Infrastructure using OpenFlow
2010 IEEE IFIP Network Operations and Management Symposium Workshops, 2010Co-Authors: Hideyuki Shimonishi, Shuji IshiiAbstract:In this paper, we present an introduction to our architecture for a virtualized Network Infrastructure and explain its enabling technologies including OpenFlow and Network OS for integrated control plane. To enable easy innovation within Network research area, Infrastructure virtualization to share a physical Infrastructure among researchers and an idea of having programmability in control plane have been paid much attention. For example, OpenFlow defines atomic behaviors for packet handing within each switching element and a protocol interface to manipulate such behaviors from a control server, thus users can program their own Network behaviors by injecting their own control programs into the server. In the same way, other protocols may be combined for optical and wireless nodes, or for Network measurement. In addition to Network control, other components in an Infrastructure, such as virtual machines or data storage, would be controllable in the same way. Therefore, by integrating such control interfaces and creating integrated control plane, we propose a basic idea for virtualized Infrastructure on which Infrastructure creators have their own virtual Infrastructure instance coupled with their own control programs on their virtualized control plane. Since on the control plane, a variety of control programs of many creators are installed to control a variety of Infrastructure components, and they sometimes cooperates for mashing-up, or are sometimes isolated for virtualization, the role of a platform software of the control plane can be complex but very important. In this paper, we propose a Network OS as a platform for such integrated control plane. It can be regarded as an OpenFlow controller but is extended to control entire Infrastructure including OpenFlow switches and other IT and Network resources. We develop a service model associated with its data structure and control module, and a model to construct a virtual Infrastructure by defining the connections among the services. Then, we briefly explain our research projects developed on the Network OS.

sensor Network Infrastructure for a home care monitoring system
Sensors, 2014Co-Authors: Filippo Palumbo, Jonas Ullberg, Ales Stimec, Francesco Furfari, Lars Karlsson, Silvia CoradeschiAbstract:This paper presents the sensor Network Infrastructure for a home care system that allows long-term monitoring of physiological data and everyday activities. The aim of the proposed system is to allow the elderly to live longer in their home without compromising safety and ensuring the detection of health problems. The system offers the possibility of a virtual visit via a teleoperated robot. During the visit, physiological data and activities occurring during a period of time can be discussed. These data are collected from physiological sensors (e.g., temperature, blood pressure, glucose) and environmental sensors (e.g., motion, bed/chair occupancy, electrical usage). The system can also give alarms if sudden problems occur, like a fall, and warnings based on more long-term trends, such as the deterioration of health being detected. It has been implemented and tested in a test environment and has been deployed in six real homes for a year-long evaluation. The key contribution of the paper is the presentation of an implemented system for ambient assisted living (AAL) tested in a real environment, combining the acquisition of sensor data, a flexible and adaptable middleware compliant with the OSGistandard and a context recognition application. The system has been developed in a European project called GiraffPlus.

SecureComm - TruSDN: Bootstrapping Trust in Cloud Network Infrastructure
Lecture Notes of the Institute for Computer Sciences Social Informatics and Telecommunications Engineering, 2017Co-Authors: Nicolae Paladi, Christian GehrmannAbstract:Software-Defined Networking (SDN) is a novel architectural model for cloud Network Infrastructure, improving resource utilization, scalability and administration. SDN deployments increasingly rely on virtual switches executing on commodity operating systems with large code bases, which are prime targets for adversaries attacking the Network Infrastructure. We describe and implement \( {\textsf{TruSDN}} \), a framework for bootstrapping trust in SDN Infrastructure using Intel Software Guard Extensions (SGX), allowing to securely deploy SDN components and protect communication between Network endpoints. We introduce ephemeral flow-specific pre-shared keys and propose a novel defense against cuckoo attacks on SGX enclaves. \( {\textsf{TruSDN}} \) is secure under a powerful adversary model, with a minor performance overhead.
