Financial Cryptography - Short Paper: Service-Oriented Sharding for Blockchains
Financial Cryptography and Data Security, 2017Co-Authors: Adem Efe Gencer, Robbert Van Renesse, Emin Gun SirerAbstract:The rise of blockchain-based cryptocurrencies has led to an explosion of services using distributed ledgers as their Underlying Infrastructure. However, due to inherently single-service oriented blockchain protocols, such services can bloat the existing ledgers, fail to provide sufficient security, or completely forego the property of trustless auditability. Security concerns, trust restrictions, and scalability limits regarding the resource requirements of users hamper the sustainable development of loosely-coupled services on blockchains.

ICICS - Opportunities for Software-Defined Networking in Smart Grid
2013 9th International Conference on Information Communications & Signal Processing, 2013Co-Authors: Jianchao Zhang, Boon-chong Seet, Tek Tjing Lie, Chuan Heng FohAbstract:The large-scale, heterogeneous, and distributed nature of the Smart Grid poses many challenges to be overcome from communication networking to autonomous control and management. The Underlying Infrastructure of Smart Grid must be efficient and reliable in transmitting large amounts of real-time data, scalable and flexible in aggregating resources, and secured and convenient in providing management interfaces to upper layer application systems. Meanwhile, the recent rapidly developing technology of Software Defined Networking (SDN) is perceived to have tremendous potential for utilization by the Underlying Infrastructure. By abstracting control functionalities from Underlying packet forwarding hardware to an external software controller, SDN offers a high degree of flexibility for implementing novel networking solutions to improve performances of distributed systems in large, complex network environments such as Smart Grid. In this paper, three potential use cases are presented to examine the opportunities for SDN technology in Smart Grid.

improving network management with software defined networking
IEEE Communications Magazine, 2013Co-Authors: Nick FeamsterAbstract:Network management is challenging. To operate, maintain, and secure a communication network, network operators must grapple with low-level vendor-specific configuration to implement complex high-level network policies. Despite many previous proposals to make networks easier to manage, many solutions to network management problems amount to stop-gap solutions because of the difficulty of changing the Underlying Infrastructure. The rigidity of the Underlying Infrastructure presents few possibilities for innovation or improvement, since network devices have generally been closed, proprietary, and vertically integrated. A new paradigm in networking, software defined networking (SDN), advocates separating the data plane and the control plane, making network switches in the data plane simple packet forwarding devices and leaving a logically centralized software program to control the behavior of the entire network. SDN introduces new possibilities for network management and configuration methods. In this article, we identify problems with the current state-of-the-art network configuration and management mechanisms and introduce mechanisms to improve various aspects of network management. We focus on three problems in network management: enabling frequent changes to network conditions and state, providing support for network configuration in a highlevel language, and providing better visibility and control over tasks for performing network diagnosis and troubleshooting. The technologies we describe enable network operators to implement a wide range of network policies in a high-level policy language and easily determine sources of performance problems. In addition to the systems themselves, we describe various prototype deployments in campus and home networks that demonstrate how SDN can improve common network management tasks.

Refactoring network Infrastructure to improve manageability: a case study of home networking
ACM SIGCOMM Computer Communication Review, 2012Co-Authors: Marshini Chetty, Nick FeamsterAbstract:Managing a home network is challenging because the Underlying Infrastructure is so complex. Existing interfaces either hide or expose the network's Underlying complexity, but in both cases, the information that is shown does not necessarily allow a user to complete desired tasks. Recent advances in software defined networking, however, permit a redesign of the Underlying network and protocols, potentially allowing designers to move complexity further from the user and, in some cases, eliminating it entirely. In this paper, we explore whether the choices of what to make visible to the user in the design of today's home network Infrastructure, performance, and policies make sense. We also examine whether new capabilities for refactoring the network Infrastructure - changing the Underlying system without compromising existing functionality - should cause us to revisit some of these choices. Our work represents a case study of how co-designing an interface and its Underlying Infrastructure could ultimately improve interfaces for that Infrastructure.

silverline data and network isolation for cloud services
IEEE International Conference on Cloud Computing Technology and Science, 2011Co-Authors: Yogesh Mundada, Anirudh Ramachandran, Nick FeamsterAbstract:Although cloud computing service providers offer opportunities for improving the administration, reliability, and maintenance of hosted services, they also concentrate network resources and data in a small number of cloud service providers. The concentration of data and resources also entails various associated risks, including sharing the Underlying Infrastructure with unknown (and untrusted) tenants and relying on the availability and security of the Underlying Infrastructure itself. These security risks represent some of the most significant barriers to the adoption of cloud-based services. To begin tackling these risks, a cloud hosting Infrastructure should provide strong guarantees for resource and data isolation. This paper examines data and network isolation problems with today's cloud hosting Infrastructures and proposes SilverLine, a collection of techniques to improve data and network isolation for a cloud tenants' service.
