Abstract | We investigate the resilience of cyber physical systems by modeling the interaction between provider and attacker as a simultaneous game that incorporates cyber and physical spaces. Both the provider and attacker aim to maximize their individual utility, which is determined by a trade-off between target revenue and investment cost. The system resilience function is formulated as a power-form product of the survival probabilities of cyber and physical spaces, each with a corresponding correlation coefficient. The contest success functions based on the reinforcement and attack levels are used to estimate the survival probabilities of cyber and physical spaces. We present the provider strategies based on the Nash equilibrium of the game, and analyze the sensitivities with respect to cyber and physical correlation coefficients, target revenues and costs. The results show that these correlation coefficients affect the cyber and physical reinforcement strategies, and also provide new insights into the system resilience. |

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.
