| Abstract | In this paper, we use hyper-network methods to identify the critical elements of a cyber-physical system (CPS) under data attack according to IEC 61850. The related works are introduced first, such as cyber offensive tools, procedures, and data attack models. Some definitions of a hypergraph are presented. Then, considering the functional attributes of logical nodes, a hyper-network model of substation auto system (SAS) is proposed using hyper-graph theory. On this basis, a CPS model that takes into account the functional influence after data attack is established. In addition, combined with the analysis of the network model, the efficiency indexes are given to evaluate the effectiveness of the CPS under data attack. The reasons why we choose these indexes in network and hyper-network model are also explained. Finally, the analysis in the case study illustrates that the method proposed is helpful for identifying critical elements of the CPS, which provides a new avenue for future vulnerability analysis research. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
