A PEV, being connected to the smart grid, can either charge its battery by consuming electricity from the grid or discharge the stored electricity from the battery to the grid. It can also participate in the frequency regulation service of the grid. Executing the aforementioned operations in a non-controlled fashion may come with problems on the grid functionality. For safe and sustainable functioning of the grid, controlling the operations is very crucial. In this paper, we are offering an approach for vehicle-to-grid management using constraint-based formal modeling. The approach is centered around an aggregator that collects all the involved parties' constraints and preferences. The aggregator then finds a management plan, i.e., a schedule of V2G services for the PEVs by satisfying the given constraints besides its own requirements. We apply satisfiability modulo theories (SMT) to synthesize the schedule as a satisfaction of the constraints. Our evaluation results show that the formalization can be efficiently solved for problems with thousands of PEVs.","PeriodicalId":303004,"journal":{"name":"ACM workshop on Smart Energy Grid Security","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115057575","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 provide support for computing non-linear functions on encrypted readings, implemented by adapting to our setting efficient secret-sharing-based secure multi-party computation techniques. Meter readings are jointly processed by a (public) storage service and a few independent authorities, each owning an additive share of the readings. For non-linear processing, these parties consume pre-shared materials, produced by an off-line trusted third party. This party never processes private readings; it may be implemented using trusted hardware or somewhat homomorphic encryption. The protocol involves minimal, off-line support from the meters---a few keyed hash computations and no communication overhead.","PeriodicalId":303004,"journal":{"name":"ACM workshop on Smart Energy Grid Security","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129013475","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}

The current DLMS/COSEM standard does not specify detailed secret key generation and distribution procedures, which induce a critical issues regarding interoperability in secure communication among AMI devices. Moreover, the protocol suffers from a key distribution problem, which can expose a session secret key supposed to be shared only by two devices to a third party node. The basic ideas are that smart meters and data collection systems perform the authentication and key exchange with AMI server using existing Extensible Authentication Protocol (EAP) standard, and DLMS/COSEM secret keys are created and shared securely using pre-formed secure channels. We show how the proposed framework can be realized in advanced metering infrastructure using existing standard protocols and provide preliminary security and performance comparisons with the existing related proposals.","PeriodicalId":303004,"journal":{"name":"ACM workshop on Smart Energy Grid Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131140005","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 light of upcoming European legislation, this approach has gained quite some attention. However, to allow such protocols to have a chance to make it into a real system, it is vital to add credibility by demonstrating that the approach scales, is reasonably robust, and can be integrated into the existing and planned smart metering chains. This paper presents results from integration and scalability tests performed on 100 DLMS/COSEM smart meters in collaboration with a meter manufacturer and a Dutch utility. We outline the use cases, lessons learned, and choices that had to be made to allow the protocols to run in a real system, as well as some privacy challenges that cannot be covered by this technology.","PeriodicalId":303004,"journal":{"name":"ACM workshop on Smart Energy Grid Security","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114852964","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 combination of two anomaly detection approaches found in the literature, one based on network flows and the other on protocol specific deep-packet inspection, seems to be able to detect many expected threats. Deep-packet inspection cannot be used however, when payloads cannot be read because they are encrypted, or the protocol is unfamiliar.\u0000 This paper proposes an intrusion detection approach that does not need to inspect the payload, and can still perform much the same function as the deep-packet approach. It consists of three steps: separate insertions caused by commands from the background of polling cycle traffic, recognize and react on known insertions, and alert on unknown insertions. The approach is implemented using searches for series of packets, based on the edit distance from approximate string matching. Tests show that this implementation can perform the steps necessary for the approach.","PeriodicalId":303004,"journal":{"name":"ACM workshop on Smart Energy Grid Security","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126450852","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 allows for effective load balancing, but at the same time threatens consumers' privacy. Since the electricity provider only needs the characteristics of a region, not individuals, approaches like one by Mármol et al. suggest to aggregate data to protect consumer privacy. However, an implementation of such an approach also has to consider the legal and regulatory situation. In Germany, the technical guideline TR-03109 issued by the Federal Office for Information Security specifies demands which have to be fulfilled so that a smart meter gateway can be certified for use. These specifications imply limitations to the protocol design. Within this paper, we discuss the applicability of the method presented by Mármol et al. under consideration of the German Smart Metering guideline. Where conformity is not given, we offer a solution to overcome these restrictions by adapting their method and introduce a third party aggregator who does not have to be trusted. Our method comes with additional communication effort but behaves well in terms of memory and computational overhead. The achieved privacy level outreaches a purely pseudonymous value transmission. Also it does not contradict the postulations of TR-03109, making it an applicable choice for privacy protection in real-world smart metering systems.","PeriodicalId":303004,"journal":{"name":"ACM workshop on Smart Energy Grid Security","volume":"29 19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121154477","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 detect such malicious commands, we propose a semantic analysis framework based on a distributed network of intrusion detection systems (IDSes). The framework combines system knowledge of both cyber and physical infrastructure in power grid to help IDS to estimate execution consequences of control commands, thus to reveal attacker's malicious intentions. We evaluated the approach on the IEEE 30-bus system. Our experiments demonstrate that: (i) by opening 3 transmission lines, an attacker can avoid detection by the traditional contingency analysis and instantly put the tested 30-bus system into an insecure state and (ii) the semantic analysis provides reliable detection of malicious commands with a small amount of analysis time.","PeriodicalId":303004,"journal":{"name":"ACM workshop on Smart Energy Grid Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130742989","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}
