Traditional identity-based cryptosystems offer scalability and security but can be computationally expensive and are complicated when it comes to private key distribution. In this paper we propose a framework based on merging physical unclonable functions (PUFs) and ID-based authentication that combines the benefits of symmetric-key cryptography with identity based cryptosystems and eliminates the risk for key compromise on the hardware level. The PUF enables meter-to-utility security at the application layer as well as secure handling of the ID-based keys. The framework relies on ID-based non-interactive key distribution mechanism to enable hop-by-hop authentication at the link layer thereby prohibiting unauthenticated packets from overloading the network. We simulated the proposed framework using an event driven network simulator in the context of wireless AMI mesh networks. The results show that our methodology is able to thwart a DoS attack by eliminating packet drops and reducing the average packet latency by 8-14×.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"58 1","pages":"933-938"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85668975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In False Data Injection (FDI) attacks, adversaries inject forged sensor measurements into a control system in hopes of misguiding control algorithms into taking dangerous actions. Traditional FDI attacks mostly require adversaries to know the full system topology, i.e., hundreds or thousands of lines and buses, while having unpredictable consequences. In this paper, we present a new class of FDI attacks directly against individual Programmable Logic Controllers (PLCs), which are ubiquitous in power generation and distribution. Our attack allows the adversary to have only partial information about the victim subsystem, and produces a predictable malicious result. Our attack tool analyzes an I/O trace of the compromised PLCs to produce a set of inputs to achieve the desired PLC outputs, i.e., the system behavior. It proceeds in two steps. First, our tool constructs a model of the PLC's internal logic from the I/O traces. Second, it searches for a set of inputs that cause the model to calculate the desired malicious behavior. We evaluate our tool against a set of representative control systems and show that it is a practical threat against insecure sensor configurations.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"47 1","pages":"848-853"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83130218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates the impact of communication on the performance of a fully distributed DC OPF algorithm, which solves the first order optimality conditions through an iterative process. In this distributed algorithm, at each iteration, every bus exchanges information with its physically connected neighboring buses and updates the local variables by evaluating a simple function. This paper suggests that sharing additional information between buses without physical connections across the system can speed up the convergence of the algorithm. A key aspect is the constrained selection of these additional communication links and the effective integration of this information in the update of the local variables which is the focus of this paper.

While the recent push for a “Smart Grid” has shown promise for increased efficiency, security has often been an after-thought, leaving this critical infrastructure vulnerable to a variety of cyber attacks. For instance, devices crucial to the safe operation of the power grid are left in remote substations with their configuration interfaces completely open, providing a vector for outsiders as well as insiders to launch an attack. This paper develops the framework for an overlay network of gateway devices that provide authenticated access control and security monitoring for these vulnerable interfaces. We develop a working prototype of such a device and simulate the performance of deployment throughout a substation. Our results suggest that such a system can be deployed with negligible impact on normal operations, while providing important security mechanisms. By doing so, we demonstrate that our proposal is a practical and efficient solution for retro-fitting security onto crucial power system devices.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"31 1","pages":"970-975"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77973260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this goal, a heterogeneous network (mixing the public Internet and private networks) is a promising solution due to its cost effectiveness. However, the current Internet infrastructure does not support reliable real time communication. To cope with these challenges, we propose QoS routing based on a novel overlay network protocol. Moreover, the protocol provides fault-tolerant communication for critical applications by applying multi-path routing over disjoint paths.

Solving it in a centralized manner not only requires high computational capabilities at the microgrid central controller (MGCC) but may also infringe customer privacy. Existing distributed approaches, on the other hand, assume that all the generations and loads are connected to one bus and ignore the underlying power distribution network and the associated power flows and system operational constraints. Consequently, the schedules produced by those algorithms may violate those constraints and thus are not feasible in practice. Therefore, the focus of this paper is on the design of a distributed energy management strategy (EMS) for the optimal operation of microgrids with consideration of the distribution network and the associated constraints. Specifically, we formulate microgrid energy management as an optimal power flow problem and propose a distributed EMS where the MGCC and the local controllers jointly compute an optimal schedule. As one demonstration, we apply the proposed distributed EMS to a real microgrid in Guangdong Province, China consisting of photovoltaics, wind turbines, diesel generators, and a battery energy storage system. The simulation results demonstrate that the proposed distributed EMS is effective in both islanded and grid-connected mode. It is also shown that the proposed algorithm converges fast.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"287 1","pages":"200-205"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74768257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We jointly manage the supply side, demand side, and DS units, taking into account the randomness of the system, and incorporating the ramping constraint of the CG. A real-time algorithm is proposed, which does not require any statistics of the system. We analytically characterize the gap between the system cost under our algorithm and the minimum cost, demonstrating that our algorithm is asymptotically optimal as the DS energy capacity increases and the CG ramping constraint loosens. In simulation, we compare the proposed algorithm with a greedy algorithm as well as a lower bound on the optimum. Simulation shows that our algorithm outperforms the greedy one and its performance can be close to the optimum even with small DS units.","PeriodicalId":6499,"journal":{"name":"2014 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":"118 1","pages":"109-114"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73295498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A PLC AMI is composed of a data concentrator and a number of meters, being restricted to a transformer substation due to the properties of current PLC technologies. However, this configuration is not suitable for other electrical networks (like American), where the number of meters per substation is very limited and the utilities are forced to install a high number of expensive data concentrators or to move to wireless technologies. To solve this problem, in this paper a new structure for PLC AMI networks, which take advantage of frequency band extension, is proposed and tested in a real environment in Colombia. Furthermore, the feasibility of deploying a metering network in this scenario is also evaluated through simulation.
