| Abstract | Studies the application of structures based on error correcting codes to systems where the major requirement is not error control but secrecy. In many cases the same code can achieve both error control and secrecy. The first section of the paper describes an optimal construction for combining multiple semi-secure channels into a single channel with much higher security. Usually the security of a communications channel cannot be guaranteed, only promised with a high degree of probability. The first section shows how to combine semi-secure channels in such a way that predetermined number may compromised before information revealed. The maximum possible secure capacity of a set of semi-secure channels is just the sum of the capacities of those channels that are in fact secure. The author presents a theorem which states that this bound on total secure capacity is, in fact, achievable. The paper proceeds to show how mixing and scrambling functions formed from error correcting codes can be used to enhance the security of trunked communications circuits and conventional cryptographic systems which depend, for their security, on unproved assertions about computational difficulty. The last segment of the paper presents a concept for applying information theoretic security to spread spectrum communications and ranging systems so that even an intended recipient of the message will not be able to jam the signal. |

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.
