| Abstract | A considerable amount of research has been carried out in harvesting the benefit of chaos theory in image encryption. However, there are not many schema that effectively maximize the advantages of Lorenz system. In this paper, we present one such image encryption algorithm that utilizes the Lorenz system for pixel manipulations. The schema employs a unique diffusion technique using Knight's tour and ensures a secure encryption with high key sensitivity. Various security checks such as histogram analysis, information entropy analysis and correlation analysis were carried out on the encrypted image. Simulation results prove that the algorithm gives excellent encryption parameters like information entropy and correlation coefficients along with the encrypted image being secure against commonly known attacks. The paper also compares the algorithm with other similar encryption methods. |

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.
